Rail-to-rail input and output and highspeed operation make them ideal for driving sampling analog-to-digital (A/D) converters. They are also wellsuited for general purpose and audio applications as well as providing I/V conversion at the output of digital-to-analog (D/A) converters. Single, dual, and quad versions have identical specifications for design flexibility.

These devices are unity-gain stable and suitable for a wide range of general-purpose applications. Rail-to-rail input and output make them ideal for driving sampling A/D converters. In addition, excellent AC performance makes them well-suited for audio applications. The class AB output stage is capable of driving 600-Ω loads series and extends 500 mV beyond the supply. Rail-to-rail input and output swing significantly increases dynamic range, especially in low-supply applications. Figure 23 shows the input and output waveforms for the OPA340 in unitygain configuration. Operation is from a single 5-V supply with a 10-kΩ load connected to V/2. The input is a 5VPP sinusoid. Output voltage is approximately 4.98 VPP. Power-supply pins must be bypassed with 0.01-µF ceramic capacitors. VS = +5, G = +1, RL = 10kW 5 2V/div VIN 5 VOUT 0 Figure 23.

However, supply voltage may range from 2.5 V to 5.5 V. Parameters are ensured over the specified supply range—a unique feature of the OPA340 series. In addition, many specifications apply from –40°C to 85°C. Most behavior remains virtually unchanged throughout the full operating voltage range. Parameters which vary significantly with operating voltages or temperature are shown in the Typical Characteristics. 7.3.2 Rail-to-Rail Input The input common-mode voltage range of the OPA340 series extends 500 mV beyond the supply rails. This extended range is achieved with a complementary input stage—an N-channel input differential pair in parallel with a P-channel differential pair. The N-channel pair is active for input voltages close to the positive rail, typically (V+) – 1.3 V to 500 mV above the positive supply, while the P-channel pair is on for inputs from 500 mV below the negative supply to approximately (V+) – 1.3 V. There is a small transition region, typically (V+) – 1.5 V to (V+) – 1.1 V, in which both pairs are on. This 400-mV transition region can vary ±300 mV with process variation. Thus, the transition region (both stages on) can range from (V+) – 1.8 V to (V+) – 1.4 V on the low end, up to (V+) – 1.2 V to (V+) – 0.8 V on the high end. OPA340 series operational amplifiers are laser-trimmed to the reduce offset voltage difference between the Nchannel and P-channel input stages, resulting in improved common-mode rejection and a smooth transition between the N-channel pair and the P-channel pair. However, within the 400-mV transition region PSRR, CMRR, offset voltage, offset drift, and THD may be degraded compared to operation outside this region. A double-folded cascode adds the signal from the two input pairs and presents a differential signal to the class AB output stage. Normally, input bias current is approximately 200 fA; however, input voltages exceeding the power supplies by more than 500 mV can cause excessive current to flow in or out of the input pins. Momentary voltages greater than 500 mV beyond the power supply can be tolerated if the current on the input pins is limited to 10 mA. This current limiting is easily accomplished with an input resistor, as shown in Figure 24. Many input signals are inherently current-limited to less than 10 mA; therefore, a limiting resistor is not required.

Input Current Protection for Voltages Exceeding the Supply Voltage 7.3.3 Rail-to-Rail Output A class AB output stage with common-source transistors is used to achieve rail-to-rail output. For light resistive loads (> 50 kΩ), the output voltage is typically a few millivolts from the supply rails. With moderate resistive loads (2 kΩ to 50 kΩ), the output can swing to within a few tens of millivolts from the supply rails and maintain high open-loop gain (see Figure 15). 7.3.4 Capacitive Load and Stability OPA340 series operational amplifiers can drive a wide range of capacitive loads. However, all operational amplifiers under certain conditions can become unstable. operational amplifier configuration, gain, and load value are some of the factors to consider when determining stability. An operational amplifier in unity-gain configuration is most susceptible to the effects of capacitive load. The capacitive load reacts with the output resistance of the operational amplifier, along with any additional load resistance, to create a pole in the small-signal response that degrades the phase margin. In unity-gain configuration, the OPA340 series operational amplifiers perform well, with a pure capacitive load up to approximately 1000 pF. Increasing gain enhances the amplifier ability to drive more capacitance (see Figure 21).

This resistor significantly reduces ringing with large capacitive loads. However, if there is a resistive load in parallel with the capacitive load, it creates a voltage divider introducing a DC error at the output and slightly reduces output swing. This error can be insignificant. For instance, with RL = 10 kΩ and RS = 20 Ω, there is only an approximate 0.2% error at the output. When used with the miniature package options of the OPA340 series, the combination is ideal for space-limited and low-power applications. For further information, consult the ADS7816 data sheet, 12-Bit High Speed Micro Power Sampling Analog-To-Digital Converter (SBAS061). With the OPA340 in a noninverting configuration, an RC network at the output of the amplifier can be used to filter high-frequency noise in the signal (see Figure 26). In the inverting configuration, filtering may be accomplished with a capacitor across the feedback resistor (see Figure 27).

However, they also offer excellent performance for higher speed converters. The OPA340 series provides an effective means of buffering the converter input capacitance and resulting charge injection while providing signal gain.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The OPAx340 amplifier is a single-supply, CMOS operational amplifier with 5.5-MHz unity-gain bandwidth and supply current of 950 µA. Its performance is optimized for low-voltage (2.7 V to 5.5 V), single-supply applications, with its input common-mode voltage linear range extending 300 mV beyond the rails and the output voltage swing within 5 mV of either rail. The OPAx340 series features wide bandwidth and unity-gain stability with rail-torail input and output for increased dynamic range. Power-supply pins must be bypassed with 0.01-µF ceramic capacitors. 8.2 Typical Applications 8.2.1 Single-Pole, Low-Pass Filter Figure 29 shows the OPA340 in a typical noninverting application with the input signal bandwidth limited by the input lowpass filter.

The simplest way to establish this limited bandwidth is to place an RC filter at the noninverting terminal of the amplifier, as shown in Figure 29. If a steeper attenuation level is required, a two-pole or higher-order filter may be used. 8.2.1.2 Detailed Design Procedure The design goals for this circuit include these parameters: • A noninverting gain of 10 V/V (20 dB) • Design a single-pole response circuit with –3-dB rolloff at 15.9 kHz and 159 Hz • Modify the design to increase attenuation level to –40 dB/decade (Sallen-Key Filter) Use these design values: • C1 = 0 nF, 10 nF, 1 µF • R1 = 1 kΩ • RG = 10 kΩ • RF = 90 kΩ Figure 30 shows how the output voltage of OPA340 changes over frequency depending on the value of C1 with a constant R1 of 1 kΩ. Without any filtering of the input signal (C1 = 0), the –3-dB effective bandwidth is a function of the OPA340 unity-gain bandwidth and closed-loop gain, f(–3dB) = UGBW/ACL, where ACL is closed-loop gain and UGBW denotes unity-gain bandwidth. Thus, for a closed-loop gain = 10, f(–3dB) = 1 MHz/10 =100 kHz; see Figure 30. To further limit the output bandwidth, an appropriate choice of C1 must be made: for C1 = 10 nF, = 15.9 kHz. To further limit the bandwidth, a larger C1 must be used: choosing C1 = 1 µF, = 159 Hz (see Figure 30). 8.2.1.3 Application Curve Gain = VOUT/VIN (dB) 40 C1 = 0 20 C1 = 10 nF 0 C1 = 1 m F -20 -40 1 10 100 1k 10 k 100 k 1M Frequency (Hz) Figure 30.

The Sallen-Key filter may be used for this task, as shown in Figure 31. For best results, the amplifier must have effective bandwidth that is at least 10 times higher than the filter cutoff frequency. Failure to follow this guideline results in a phase shift of the amplifier, which in turn leads to lower precision of the filter bandwidth. Additionally, to minimize the loading effect between multiple RC pairs on overall the filter cutoff frequency, choose R = 10 × R1 and C2 = C1/10; see Figure 32. Figure 31. Two-Pole, Lowpass Filter Equation 3 through Equation 5 show calculations for corner frequency and gain: (3) (4) (5) 8.2.2.1 Detailed Design Procedure Use these design values: • C1 = 10 nF and C2 = 1 nF • R1 = 1 kΩ and R2= 10 kΩ • RG = 10 kΩ • RF = 90 kΩ Figure 32 shows the Sallen-Key filter second-order response for different RC values: for R and C values above, = 15.9 kHz. To further limit the bandwidth, a larger RC value must be used: increasing C values 100 times, such as C1 = 1 µF and C2 = 0.1 µF, with unchanged resistors, results in the second-order rolloff at = 159 Hz.

CAUTION Supply voltages larger than 7 V can permanently damage the device (see the Absolute Maximum Ratings). TI recommends placing 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high-impedance power supplies.

Keep traces short and when possible, use a printed-circuit board (PCB) ground plane with surface-mount components placed as close to the device pins as possible. Place a 0.1-μF capacitor closely across the supply pins. Apply these guidelines throughout the analog circuit to improve performance and provide benefits, such as reducing the electromagnetic interference (EMI) susceptibility. Operational amplifiers vary in susceptibility to radio frequency interference (RFI). RFI can generally be identified as a variation in offset voltage or DC signal levels with changes in the interfering RF signal. The OPA340 is specifically designed to minimize susceptibility to RFI and demonstrates remarkably low sensitivity compared to previous generation devices. Strong RF fields can still cause varying offset levels. 10.2 Layout Example Place components close to device and to eachother to reduce parasitic errors Run the input traces as far away from the supply lines as possible VS+ RF N/C N/C GND –IN V+ VIN +IN OUTPUT V– N/C RG GND GND Use low-ESR, ceramic bypass capacitor VS– Use low-ESR, ceramic bypass capacitor VOUT Copyright © 2016, Texas Instruments Incorporated Figure 33.
