Additionally, the LMV861 and LMV862 are EMI hardened to minimize any interference so they are ideal for EMI sensitive applications. The unity gain stable LMV861 and LMV862 feature 30 MHz of bandwidth while consuming only 2.25 mA of current per channel. These parts also maintain stability for capacitive loads as large as 200 pF. The LMV861 and LMV862 provide superior performance and economy in terms of power and space usage. This family of parts has a maximum input offset voltage of 1 mV, a rail-to-rail output stage and an input common-mode voltage range that includes ground. Over an operating range from 2.7V to 5.5V the LMV861 and LMV862 provide a PSRR of 93 dB, and a CMRR of 93 dB. The LMV861 is offered in the space saving 5-Pin SC70 package, and the LMV862 in the 8-Pin VSSOP.

These specifications make the LMV861 and LMV862 great choices for medical and instrumentation applications such as diagnosis equipment and power line monitors. The low supply current is perfect for battery powered equipment. The small packages, SC70 package for the LMV861, and the VSSOP package for the dual LMV862, make these parts a perfect choice for portable electronics. Additionally, the EMI hardening makes the LMV861 and LMV862 a must for almost all op amp applications. Most applications are exposed to Radio Frequency (RF) signals such as the signals transmitted by mobile phones or wireless computer peripherals. The LMV861 and LMV862 will effectively reduce disturbances caused by RF signals to a level that will be hardly noticeable. This again reduces the need for additional filtering and shielding. Using this EMI resistant series of op amps will thus reduce the number of components and space needed for applications that are affected by EMI, and will help applications, not yet identified as possible EMI sensitive, to be more robust for EMI. INPUT CHARACTERISTICS The input common mode voltage range of the LMV861 and LMV862 includes ground, and can even sense well below ground. The CMRR level does not degrade for input levels up to 1.2V below the supply voltage. For a supply voltage of 5V, the maximum voltage that should be applied to the input for best CMRR performance is thus 3.8V. When not configured as unity gain, this input limitation will usually not degrade the effective signal range. The output is rail-to-rail and therefore will introduce no limitations to the signal range. The typical offset is only 0.273 mV, and the TCVOS is 0.7 μV/°C, specifications close to precision op amps. CMRR MEASUREMENT The CMRR measurement results may need some clarification. This is because different setups are used to measure the AC CMRR and the DC CMRR. The DC CMRR is derived from ΔVOS versus ΔVCM. This value is stated in the tables, and is tested during production testing. The AC CMRR is measured with the test circuit shown in Figure 44. R2 1 k: + V + R1 1 k: - VIN LMV86x + R11 1 k: V BUFFER Buffer + VOUT - R12 V995: V BUFFER P1 10: Figure 44. AC CMRR Measurement Setup The configuration is largely the usually applied balanced configuration. With potentiometer P1, the balance can be tuned to compensate for the DC offset in the DUT. The main difference is the addition of the buffer. This buffer prevents the open-loop output impedance of the DUT from affecting the balance of the feedback network. Now the closed-loop output impedance of the buffer is a part of the balance. But as the closed-loop output impedance is much lower, and by careful selection of the buffer also has a larger bandwidth, the total effect is that the CMRR of the DUT can be measured much more accurately. The differences are apparent in the larger measured bandwidth of the AC CMRR.

This is because in the AC CMRR test circuit the potentiometer is used to compensate for the DC mismatches. So, mainly AC mismatch is all that remains. Therefore, the obtained DC CMRR from this AC CMRR test circuit tends to be higher than the actual DC CMRR based on DC measurements. The CMRR curve in Figure 45 shows a combination of the AC CMRR and the DC CMRR. AC CMRR 100 CMRR (dB) 80 DC CMRR 60 40 20 + V = 3.3V, 5.0V 100 1k 10k 100k FREQUENCY (Hz) 1M 10M Figure 45. CMRR Curve OUTPUT CHARACTERISTICS As already mentioned the output is rail-to-rail. When loading the output with a 10 kΩ resistor the maximum swing of the output is typically 3 mV from the positive and negative rail. The output of the LMV861 and LMV862 can drive currents up to 70 mA at 3.3V, and even up to 150 mA at 5V. The LMV861 and LMV862 can be connected as non-inverting unity gain amplifiers. This configuration is the most sensitive to capacitive loading. The combination of a capacitive load placed at the output of an amplifier along with the amplifier’s output impedance creates a phase lag, which reduces the phase margin of the amplifier. If the phase margin is significantly reduced, the response will be under damped which causes peaking in the transfer and, when there is too much peaking, the op amp might start oscillating. The LMV861 and LMV862 can directly drive capacitive loads up to 200 pF without any stability issues. In order to drive heavier capacitive loads, an isolation resistor, RISO, should be used, as shown in Figure 46. By using this isolation resistor, the capacitive load is isolated from the amplifier’s output, and hence, the pole caused by CL is no longer in the feedback loop. The larger the value of RISO, the more stable the amplifier will be. If the value of RISO is sufficiently large, the feedback loop will be stable, independent of the value of CL. However, larger values of RISO result in reduced output swing and reduced output current drive. VIN RISO VOUT + CL Figure 46. Isolating Capacitive Load A resistor value of around 50Ω would be sufficient. As an example some values are given in the following table, for 5V and an open loop gain of 111 dB. 14 CLOAD RISO 300 pF 62Ω 400 pF 55Ω 500 pF 50Ω Submit Documentation Feedback Copyright © 2008–2013, Texas Instruments Incorporated Product Folder Links: LMV861 LMV862 LMV861, LMV862 www.ti.com SNOSAZ5C – FEBRUARY 2008 – REVISED MARCH 2013 When increasing the closed-loop gain the capacitive load can be increased even further. With a closed loop gain of 2 and a 27Ω isolation resistor, the load can be 1 nF EMIRR With the increase of RF transmitting devices in the world, the electromagnetic interference (EMI) between those devices and other equipment becomes a bigger challenge. The LMV861 and LMV862 are EMI hardened op amps which are specifically designed to overcome electromagnetic interference. Along with EMI hardened op amps, the EMIRR parameter is introduced to unambiguously specify the EMI performance of an op amp. This section presents an overview of EMIRR. A detailed description on this specification for EMI hardened op amps can be found in Application Note AN-1698. The dimensions of an op amp IC are relatively small compared to the wavelength of the disturbing RF signals. As a result the op amp itself will hardly receive any disturbances. The RF signals interfering with the op amp are dominantly received by the PCB and wiring connected to the op amp. As a result the RF signals on the pins of the op amp can be represented by voltages and currents. This representation significantly simplifies the unambiguous measurement and specification of the EMI performance of an op amp. RF signals interfere with op amps via the non-linearity of the op amp circuitry. This non-linearity results in the detection of the so called out-of-band signals. The obtained effect is that the amplitude modulation of the out-ofband signal is downconverted into the base band. This base band can easily overlap with the band of the op amp circuit. As an example Figure 47 depicts a typical output signal of a unity-gain connected op amp in the presence of an interfering RF signal. Clearly the output voltage varies in the rhythm of the on-off keying of the RF carrier. RF RF SIGNAL VOUT OPAMP (AV = 1) NO RF VOS + VDETECTED VOS Figure 47. Offset voltage variation due to an interfering RF signal EMIRR Definition To identify EMI hardened op amps, a parameter is needed that quantitatively describes the EMI performance of op amps. A quantitative measure enables the comparison and the ranking of op amps on their EMI robustness. Therefore the EMI Rejection Ratio (EMIRR) is introduced. This parameter describes the resulting input-referred offset voltage shift of an op amp as a result of an applied RF carrier (interference) with a certain frequency and level. The definition of EMIRR is given by: §V · RF_PEAK ¸ EMIRRV RF_PEAK = 20 log ¨ ¸ ¨ 'V OS ¹ © where • • VRF_PEAK is the amplitude of the applied un-modulated RF signal (V) ΔVOS is the resulting input-referred offset voltage shift (V) (1) The offset voltage depends quadratically on the applied RF level, and therefore, the RF level at which the EMIRR is determined should be specified. The standard level for the RF signal is 100 mVP. Application Note AN-1698 addresses the conversion of an EMIRR measured for an other signal level than 100 mVP. The interpretation of the EMIRR parameter is straightforward. When two op amps have EMIRRs which differ by 20 dB, the resulting error signals when used in identical configurations, differs by 20 dB as well. So, the higher the EMIRR, the more robust the op amp.

In this section the measurements on the IN+ pin (which, based on symmetry considerations, also apply to the IN- pin) are discussed. In Application Note AN-1698 the other pins of the op amp are treated as well. For testing the IN+ pin the op amp is connected in the unity gain configuration. Applying the RF signal is straightforward as it can be connected directly to the IN+ pin. As a result the RF signal path has a minimum of components that might affect the RF signal level at the pin. The circuit diagram is shown in Figure 48. The PCB trace from RFIN to the IN+ pin should be a 50Ω stripline in order to match the RF impedance of the cabling and the RF generator. On the PCB a 50Ω termination is used. This 50Ω resistor is also used to set the bias level of the IN+ pin to ground level. For determining the EMIRR, two measurements are needed: one is measuring the DC output level when the RF signal is off; and the other is measuring the DC output level when the RF signal is switched on. The difference of the two DC levels is the output voltage shift as a result of the RF signal. As the op amp is in the unity gain configuration, the input referred offset voltage shift corresponds one-to-one to the measured output voltage shift.

Circuit for coupling the RF signal to IN+ Cell Phone Call The effect of electromagnetic interference is demonstrated in a setup where a cell phone interferes with a pressure sensor application. The application is show in Figure 50. This application needs two op amps and therefore a dual op amp is used. The op amp configured as a buffer and connected at the negative output of the pressure sensor prevents the loading of the bridge by resistor R2. The buffer also prevents the resistors of the sensor from affecting the gain of the following gain stage. The op amps are placed in a single supply configuration. The experiment is performed on two different op amps: a typical standard op amp and the LMV862, EMI hardened dual op amp. A cell phone is placed on a fixed position a couple of centimeters from the op amps in the sensor circuit. When the cell phone is called, the PCB and wiring connected to the op amps receive the RF signal. Subsequently, the op amps detect the RF voltages and currents that end up at their pins. The resulting effect on the output of the second op amp is shown in Figure 49. 16 Submit Documentation Feedback Copyright © 2008–2013, Texas Instruments Incorporated Product Folder Links: LMV861 LMV862 LMV861, LMV862 SNOSAZ5C – FEBRUARY 2008 – REVISED MARCH 2013 VOUT (0.5V/DIV) www.ti.com Typical Opamp LMV862 TIME (0.5s/DIV) Figure 49. Comparing EMI Robustness The difference between the two types of op amps is clearly visible. The typical standard dual op amp has an output shift (disturbed signal) larger than 1V as a result of the RF signal transmitted by the cell phone. The LMV862, EMI hardened op amp does not show any significant disturbances. This means that the RF signal will not disturb the signal entering the ADC when using the LMV862. R1 2.4 k: VDD VDD PRESSURE SENSOR + LMV862 - + R2 100: ADC LMV862 + VOUT Figure 50. Pressure Sensor Application DECOUPLING AND LAYOUT Care must be given when creating a board layout for the op amp. For decoupling the supply lines it is suggested that 10 nF capacitors be placed as close as possible to the op amp. For single supply, place a capacitor between V+ and V−. For dual supplies, place one capacitor between V+ and the board ground, and a second capacitor between ground and V−. Even with the LMV861 and LMV862 inherent hardening against EMI, it is still recommended to keep the input traces short and as far as possible from RF sources. Then the RF signals entering the chip are as low as possible, and the remaining EMI can be, almost, completely eliminated in the chip by the EMI reducing features of the LMV861 and LMV862. LOAD CELL SENSOR APPLICATION The LMV861 and LMV862 can be used for weight measuring system applications which use a load cell sensor. Examples of such systems are: bathroom weight scales, industrial weight scales and weight measurement devices on moving equipment such as forklift trucks. The following example describes a typical load cell sensor application that can be used as a starting point for many different types of sensors and applications. Applications in environments where EMI may appear would especially benefit from the EMIRR performance of the LMV861 and LMV862.

The value of the resistors in the bridge changes when pressure is applied to the sensor. This change of the resistor values will result in a differential output voltage depending on the sensitivity of the sensor, the used supply voltage and the applied pressure. The difference between the output at full scale pressure and the output at zero pressure is defined as the span of the load cell. A typical value for the span is 10 mV/V. The circuit configuration should be chosen such that loading of the sensor is prevented. Loading of the resistor bridge due to the circuit following the sensor, could result in incorrect output voltages of the sensor. Load Cell Example Figure 51 shows a typical schematic for a load cell application. It uses a single supply and has an adjustment for both positive and negative offset of the load cell. An ADC converts the amplified signal to a digital signal. The op amps A1 and A2 are configured as buffers, and are connected at both the positive and the negative output of the load cell. This is to prevent the loading of the resistor bridge in the sensor by the resistors configuring the differential op amp circuit (op amp A4). The buffers also prevent the resistors of the sensor from affecting the gain of the following gain stage. The third buffer (A3) is used to create a reference voltage, to correct for the offset in the system. Given the differential output voltage VS of the load cell, the output signal of this op amp configuration, VOUT, equals: R3 x V R3 R3 x VDD SENSE + § VOUT = + 1 x VREF R1 © R5 R5 (2) § © To align the pressure range with the full range of an ADC the correct gain needs to be set. To calculate the correct gain, the power supply voltage and the span of the load cell are needed. For this example a power supply of 5V is used and the span of the sensor, in this case a 125 kg sensor, is 100 mV. With the configuration as shown in Figure 51, this signal is covering almost the full input range of the ADC. With no weight on the load cell, the output of the sensor and the op amp A4 will be close to 0V. With the full weight on the load cell, the output of the sensor is 100 mV, and will be amplified with the gain from the configuration. In the case of the configuration of Figure 51 the gain is R3/R1 = 51 kΩ/100Ω = 50. This will result in a maximum output of 100 mV x 50 = 5V, which covers the full range of the ADC. For further processing the digital signal can be processed by a microprocessor following the ADC, this can be used to display or log the weight on the load cell. To get a resolution of 0.5 kg, the LSB of the ADC should be smaller then 0.5 kg/125 kg = 1/1000. A 12-bit ADC would be sufficient as this gives 4096 steps. A 12-bit ADC such as the two channel 12-bit ADC122S021 can be used for this application. 18 Submit Documentation Feedback Copyright © 2008–2013, Texas Instruments Incorporated Product Folder Links: LMV861 LMV862 LMV861, LMV862 www.ti.com SNOSAZ5C – FEBRUARY 2008 – REVISED MARCH 2013 VDD R5 5 k: VDD A1 - LOAD CELL + R3 5 k: R1 100: VDD LMV861 - + A4 ADC LMV861 VSENSE A2 - + R2 100: VOUT LMV861 + R4 5 k: VDD R6 80 k: P1 20 k: A3 - VREF LMV861 + R6 80 k: Figure 51. Load Cell Application IR PHOTODIODE APPLICATION The LMV861 and LMV862 are also very good choices to be used in photodiode applications, such as IR communication, monitoring, etc. The large bandwidth of the LMV861 and LM862 makes it possible to create high speed detection. This, together with the low noise, makes the LMV861 and LMV862 ideal for medical applications such as fetal monitors and bed side monitors. Another application where the LMV861 and LMV862 would fit perfectly is a bill validator, an instrument to detect counterfeit bank notes. The following example describes an application that can be used for different types of photodiode sensors and applications. IR Photodiode Example The circuit shown in Figure 53 is a typical configuration for the readout of a photodiode. The response of a photodiode to incoming light is a variation in the diode current. In many applications a voltage is required, i.e. when connecting to an ADC. Therefore the first step is to convert the diode signal current into a voltage by an I-V converter. In Figure 53 the left op amp is configured as an I-V converter, with a gain set by R1. Some types of photodiodes can have a large capacitance. This could potentially lead to oscillation. The addition of resistor R2 isolates the photodiode capacitance from the feedback loop, thereby preventing the loop from oscillating. The capacitor in between the two op amp configurations, blocks the DC component, thus removing the DC offset of the first op amp circuit, and the offset created by the ambient light entering the photodiode. The second op amp amplifies the signal to levels that can be converted to a digital signal by an ADC. To prevent floating of the input of the second op amp, resistor R5 is added. By allowing the input bias current of a few pA to flow through this resistor a stable input is ensured. In Figure 52 a sensed and amplified signal is shown from an IR source, in this case an IR remote control. The data from the ADC can then be used by a DSP or microprocessor for further processing.
