Typical Applications
LMV932MMX/NOPB is suitable for 6 applications: Portable Battery-Powered Sensor Front End, Mobile Phone and Tablet Audio/Sensor Circuitry, Active Filter Stages in Low-Voltage Systems, Industrial Sensor Signal Conditioning, Comparators and Threshold Detectors (Op Amp as Comparator), ADC Driver for Low-Speed Data Converters.
Portable Battery-Powered Sensor Front End
In two-cell alkaline or single-cell Li-Ion products, the supply can sag to 1.8V near end of discharge; the LMV932MMX/NOPB is guaranteed to operate at that level with rail-to-rail input and output, preserving signal swing as the battery drains. Used as a non-inverting amplifier between a bridge or resistive sensor and an ADC, its RRIO input accepts signals at or near ground while the output swings within millivolts of the rails, maximizing ADC code utilization. The 1.5MHz gain-bandwidth comfortably handles low-frequency sensor signals, and the compact VSSOP-8 package fits dense handheld PCBs.
Recommended
Mobile Phone and Tablet Audio/Sensor Circuitry
TI explicitly targets the LMV93x-N family at mobile phones and tablets because the 8-pin VSSOP and low-voltage operation suit area-constrained, battery-driven boards. In handsets the dual channel lets one side buffer a microphone or sensor signal while the second stage implements an active anti-aliasing filter, doubling channel density versus single amps. The 1.8V to 5.5V range matches the 1.8V digital rails common in mobile platforms, eliminating a dedicated higher-voltage analog supply, and the 5mA output capability is adequate for driving filters and ADC inputs in these signal chains.
Recommended
Active Filter Stages in Low-Voltage Systems
Sallen-Key and multiple-feedback filters built with the LMV932MMX/NOPB work well at 1.8V to 5.5V because the RRIO output maximizes headroom for filter response at low supplies, avoiding clipping on signals near the rails. With 1.5MHz gain-bandwidth, low-order filters with cutoffs up to tens of kilohertz and gains of 1 to 5 achieve accurate response; designers should budget GBW margin (typically 100x the cutoff times the Q) for precision filters. Both channels in the VSSOP-8 enable second-order sections in a single tiny footprint, ideal for anti-aliasing before low-speed ADCs.
Recommended
Industrial Sensor Signal Conditioning
Across the -40C to +125C industrial temperature range, the LMV932MMX/NOPB conditions 4-20mA receiver voltages, thermistor dividers, and pressure-sensor outputs on 3.3V or 5V rails. Its rail-to-rail input tolerates common-mode signals all the way to the positive rail, which simplifies high-side current-sense resistor buffering at low supply voltages where conventional amplifiers run out of headroom. Distributor data notes an automotive temperature grade for the package option, supporting extended-reliability industrial programs. The 5mA output can directly drive comparison thresholds, LED indicators, or additional filter stages.
Recommended
Comparators and Threshold Detectors (Op Amp as Comparator)
One LMV932MMX/NOPB channel can serve as a low-voltage threshold detector with hysteresis while the other remains available for amplification, a common board-consolidation technique in cost-sensitive designs. The RRIO input means trip points can be set very close to either rail using resistor dividers on 1.8V to 5.5V supplies. Note that a general-purpose op amp is slower than a dedicated comparator; at 1.5MHz GBW, response times are in the microsecond range, adequate for supervisory and level-detection functions but not for fast logic-level signaling, where a purpose-built comparator should be used instead.
Recommended
ADC Driver for Low-Speed Data Converters
Before a SAR or delta-sigma ADC operating at 1.8V to 5V, the LMV932MMX/NOPB buffers sensor signals and drives the sampling network through an RC charge-kickback filter. Its rail-to-rail output preserves full-scale range, and the 5mA output current handles typical 10-100kohm effective input impedances. For sample rates below roughly 100ksps with settling budgets of a few microseconds, the 1.5MHz GBW is sufficient in gains up to about 4x; beyond that, select a wider-bandwidth dual such as the TLV9152 in the identical VSSOP-8 footprint for a direct upgrade without PCB redesign.

Key Differentiators
- True 1.8V minimum supply (vs TLV2452AIDGKR-Q1)
- Rail-to-rail input AND output (vs OPA2172)
- Lower cost general-purpose positioning (vs TLV9152IDGKR)
Design Notes
The 1.5MHz gain-bandwidth limits closed-loop performance: a gain-of-10 stage delivers only ~150kHz of bandwidth before rolloff, so verify loop gain margin for gains above 5 and for filter Q values above 1. Do not use this general-purpose op amp where a dedicated comparator is needed for fast switching - response will be in the microsecond range.
Keep load impedance above several kilohms, especially at 1.8V supply where the 5mA output-current capability and voltage headroom are both limited. Rail-to-rail output swing degrades under heavy load, reducing usable dynamic range; for driving ADC inputs, use an RC isolation resistor (tens of ohms) at the output.
Place 100nF ceramic decoupling capacitors within 2mm of the V+ pin on pin 8 with a low-impedance ground return to pin 4. The VSSOP-8 has a 1.27mm pin pitch on 3x3mm body - keep analog input traces short and guard the high-impedance inverting node with ground pour to limit leakage and noise pickup.
Compliance Information
