The LMV93x-N-Q1 family operates from 1.8-V to 5.5-V supply voltages and have rail-to-rail input and output. The input common-mode voltage extends 200 mV beyond the supplies which enables user enhanced functionality beyond the supply voltage range. The output can swing rail-to-rail unloaded and within 105 mV from the rail with 600-Ω load at 1.8-V supply. The LMV93x-N-Q1 devices are optimized to work at 1.8 V, which make them ideal for portable two-cell, battery-powered systems and single-cell Li-Ion systems. 1 • • • • • • • • • • Qualified for Automotive Applications AEC-Q100 Qualified With the Following Results: – Device Temperature Grade 1: –40°C to +125°C Ambient Operating Temperature – Device HBM ESD Classification Level 02 – Device CDM ESD Classification Level C5 Typical 1.8-V Supply Values; Unless Otherwise Noted Specified at 1.8 V, 2.7 V, and 5 V Output Swing – With 600-Ω Load 80 mV from Rail – With 2-kΩ Load 30 mV from Rail VCM 200 mV Beyond Rails Supply Current (per Channel) 100 μA Gain Bandwidth Product 1.4 MHz Maximum VOS 4 mV Ultra Tiny Packages Temperature Range −40°C to +125°C Create a Custom Design Using the LMV93x-N-Q1 With the WEBENCH® Power Designer 2 Applications • • • • • • Engine Control Units (ECU) Body Control Modules (BCM) Battery Management Systems (BMS) Ultrasonic Ranging and LIDAR Occupant Detection Infotainment Systems High-Side Current Sense Amplifier LMV93x-N-Q1 devices exhibit an excellent speedpower ratio, achieving 1.4-MHz gain bandwidth product at 1.8-V supply voltage with very low supply current.

LMV93x-Q1-N input common-mode voltage extends 200 mV beyond the supplies which enables user enhanced functionality beyond the supply voltage range. 7.2 Functional Block Diagram V IN – IN + + _ OUT + V – Copyright © 2016, Texas Instruments Incorporated (Each Amplifier) 7.3 Feature Description The differential inputs of the amplifier consist of a noninverting input (+IN) and an inverting input (–IN). The amplifer amplifies only the difference in voltage between the two inputs, which is called the differential input voltage. The output voltage of the op-amp VOUT is given by Equation 1: VOUT = AOL (IN+ - IN-) where • AOL is the open-loop gain of the amplifier, typically around 100 dB (100,000x, or 10 µV per volt). (1) 7.4 Device Functional Modes 7.4.1 Input and Output Stage The rail-to-rail input stage of this family provides more flexibility for the designer. The LMV93x-Q1-N use a complimentary PNP and NPN input stage in which the PNP stage senses common-mode voltage near V− and the NPN stage senses common-mode voltage near V+. The transition from the PNP stage to NPN stage occurs 1 V below V+. Because both input stages have their own offset voltage, the offset of the amplifier becomes a function of the input common-mode voltage and has a crossover point at 1 V below V+. 16 Submit Documentation Feedback Copyright © 2017, Texas Instruments Incorporated Product Folder Links: LMV931-N-Q1 LMV932-N-Q1 LMV934-N-Q1 LMV931-N-Q1 LMV932-N-Q1, LMV934-N-Q1 www.ti.com SNOSD49 – MAY 2017 Device Functional Modes (continued) Copyright © 2016, Texas Instruments Incorporated Figure 29. Simplified Schematic Diagram This VOS crossover point can create problems for both DC− and AC-coupled signals if proper care is not taken. Large input signals that include the VOS crossover point will cause distortion in the output signal. One way to avoid such distortion is to keep the signal away from the crossover. For example, in a unity gain buffer configuration with VS = 5 V, a 5-V peak-to-peak signal will contain input-crossover distortion while a 3-V peak-topeak signal centered at 1.5 V will not contain input-crossover distortion as it avoids the crossover point. Another way to avoid large signal distortion is to use a gain of −1 circuit which avoids any voltage excursions at the input terminals of the amplifier. In that circuit, the common-mode DC voltage can be set at a level away from the VOS cross-over point. For small signals, this transition in VOS shows up as a VCM dependent spurious signal in series with the input signal and can effectively degrade small signal parameters such as gain and common-mode rejection ratio. To resolve this problem, the small signal should be placed such that it avoids the VOS crossover point. In addition to the rail-to-rail performance, the output stage can provide enough output current to drive 600Ω loads. Because of the high-current capability, take care not to exceed the 150°C maximum junction temperature specification. 7.4.2 Input Bias Current Consideration The LMV93x-Q1-N family has a complementary bipolar input stage. The typical input bias current (IB) is 15 nA. The input bias current can develop a significant offset voltage. This offset is primarily due to IB flowing through the negative feedback resistor, RF. For example, if IB is 50 nA and RF is 100 kΩ, then an offset voltage of 5 mV will develop (VOS = IB x RF). Using a compensation resistor (RC), as shown in Figure 30, cancels this effect. But the input offset current (IOS) will still contribute to an offset voltage in the same manner.

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 LMV93x-Q1-N devices bring performance, economy and ease-of-use to low-voltage, low-power systems. They provide rail-to-rail input and rail-to-rail output swings into heavy loads. 8.2 Typical Applications 8.2.1 High-Side Current-Sensing Application Figure 31. High-Side Current Sensing 8.2.1.1 Design Requirements The high-side current-sensing circuit (Figure 31) is commonly used in a battery charger to monitor charging current to prevent overcharging. A sense resistor RSENSE is connected to the battery directly. This system requires an op amp with rail-to-rail input. The LMV93x-Q1-N are ideal for this application because its commonmode input range extends up to the positive supply. 8.2.1.1.1 Custom Design With WEBENCH® Tools Click here to create a custom design using the LMV93x-Q1-N device with the WEBENCH® Power Designer. 1.

The voltage at the negative sense point will now be less than the positive sense point by an amount proportional to the VSENSE voltage. The low-bias currents of the LMV93x-Q1-Q1 cause little voltage drop through R2, so the negative input of the LMV93x-Q1 amplifier is at essentially the same potential as the negative sense input. The LMV93x-Q1 will detect this voltage error between its inputs and servo the transistor base to conduct more current through Q1, increasing the voltage drop across R1 until the LMV93x-Q1 inverting input matches the noninverting input. At this point, the voltage drop across R1 now matches VSENSE. IG, a current proportional to ICHARGE, will flow according to the following relation: IG = VRSENSE / R1 = ( RSENSE * ICHARGE ) / R1 (2) IG also flows through the gain resistor R3 developing a voltage drop equal to: V3 = IG * R3 = ( VRSENSE / R1 ) * R3 = ( ( RSENSE * ICHARGE ) / R2 ) * R3 VOUT = (RSENSE * ICHARGE ) * G (3) where • G = R3 / R1 (4) The other channel of the LMV93x-Q1 may be used to buffer the voltage across R3 to drive the following stages. 8.2.1.3 Application Curve Figure 32 shows the results of the example current sense circuit. 5 VOUT (V) 4 3 2 1 0 0 1 2 3 4 5 ICHARGE (A) C001 NOTE: the error after 4 V where transistor Q1 runs out of headroom and saturates, limiting the upper output swing.

Half-Wave Rectifier With Negative-Going Output Referenced to VCC 8.2.2.1 Design Requirements Because the LMV931-N-Q1, LMV932-N-Q1, LMV934-N-Q1 input common-mode range includes both positive and negative supply rails and the output can also swing to either supply, achieving half-wave rectifier functions in either direction is an easy task. All that is needed are two external resistors; there is no need for diodes or matched resistors. The half-wave rectifier can have either positive or negative going outputs, depending on the way the circuit is arranged. 8.2.2.2 Detailed Design Procedure In Figure 33 the circuit is referenced to ground, while in Figure 34 the circuit is biased to the positive supply. These configurations implement the half-wave rectifier because the LMV93x-Q1-N can not respond to one-half of the incoming waveform. It can not respond to one-half of the incoming because the amplifier cannot swing the output beyond either rail therefore the output disengages during this half cycle. During the other half cycle, however, the amplifier achieves a half wave that can have a peak equal to the total supply voltage. RI should be large enough not to load the LMV93x-Q1-N. 8.2.2.3 Application Curve Figure 35. Output of Ground-to-Rail Circuit Copyright © 2017, Texas Instruments Incorporated Figure 36.

Rail-to-Rail Instrumentation Amplifier 8.2.3.1 Design Requirements Using three of the LMV93x-Q1-N amplifiers, an instrumentation amplifier with rail-to-rail inputs and outputs can be made as shown in Figure 37. 8.2.3.2 Detailed Design Procedure In this example, amplifiers on the left side act as buffers to the differential stage. These buffers assure that the input impedance is very high. They also assure that the difference amp is driven from a voltage source. This is necessary to maintain the CMRR set by the matching R1-R2 with R3-R4. The gain is set by the ratio of R2 / R1 and R3 must equal R1 and R4 equal R2. With both rail-to-rail input and output ranges, the input and output are only limited by the supply voltages. Remember that even with rail-to-rail outputs, the output can not swing past the supplies so the combined common-mode voltages plus the signal must not be greater that the supplies or limiting will occur. 8.2.3.3 Application Curve Figure 38 shows the results of the instrumentation amplifier with R1 and R3 = 1 K, and R2 and R4 = 100 kΩ, for a gain of 100, running on a single 5-V supply with a input of VCM = VS/2. The combined effects of the individual offset voltages can be seen as a shift in the offset of the curve. 5 VOUT (V) 4 3 2 1 0 0 10 20 30 VDIFF (mV) 40 50 C001 Figure 38.

Do add series resistence to the output when driving capacitive loads, particularly cables, Muxes and ADC inputs. Do add series current limiting resistors and external schottky clamp diodes if input voltage is expected to exceed the supplies. Limit the current to 1 mA or less (1 kΩ per volt). 9 Power Supply Recommendations For proper operation, the power supplies must be properly decoupled. For decoupling the supply lines, TI recommends that 10-nF capacitors be placed as close as possible to the op amp power supply pins. For singlesupply, place a capacitor between V+ and V− supply leads. For dual supplies, place one capacitor between V+ and ground, and one capacitor between V– and ground.

The optimum placement is closest to the V+ and ground pins. Take care to minimize the loop area formed by the bypass capacitor connection between V+ and ground. The ground pin must be connected to the PCB ground plane at the pin of the device.
