Product details
Overview
LMV932MA/NOPB from Texas Instruments is a dual, rail-to-rail input/output operational amplifier optimized for 1.8-V operation, delivering 1.4-MHz gain bandwidth, 100-μA per-channel supply current, and output swing within 105 mV of rails under 600-Ω load - enabling precision signal conditioning in space-constrained, battery-powered systems such as wearable health monitors and portable instrumentation.
For engineers reviewing the LMV932MA/NOPB datasheet, LMV932MA/NOPB pinout, LMV932MA/NOPB application, or LMV932MA/NOPB equivalent, key selection criteria include its ultra-low 1.8-V minimum supply, −40°C to +125°C operating range, rail-to-rail common-mode input extending 200 mV beyond supplies, and verified stability driving up to 1000-pF capacitive loads - critical for low-power sensor front-ends and ADC driver stages.
Technical Context
The LMV932MA/NOPB implements a CMOS input stage with rail-to-rail input common-mode range (V− − 0.2 V to V+ + 0.2 V at 25°C) and complementary bipolar output stage enabling true rail-to-rail output swing. Its 1.4-MHz unity-gain bandwidth and 0.35-V/μs slew rate at 1.8 V are achieved with only 103–205 μA per channel, balancing speed and power for single-cell Li-ion and two-cell alkaline applications.
Designed for single-supply operation down to 1.8 V, it maintains DC precision with 1–5.5-mV max input offset voltage, 75–101-dB CMRR over extended common-mode range, and 75–100-dB PSRR - supporting accurate amplification of low-level sensor signals without level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct interface with single-cell Li-ion (2.7–4.2 V), two-cell alkaline (2.4–3.2 V), and 1.8-V logic domains without LDOs. |
| Gain Bandwidth Product | 1.4 MHz at 1.8 V - enables stable unity-gain buffer or gain-of-10 amplification up to ~140 kHz for ECG, pulse oximetry, or temperature sensor signals. |
| Supply Current per Channel | 103–205 μA - allows dual-amplifier operation on <200 μA total, ideal for coin-cell or energy-harvesting systems with multi-day battery life. |
| Input Offset Voltage | Max 5.5 mV (full temperature range) - ensures ≤0.5% error in 1-V full-scale sensor outputs without trimming. |
| Output Swing (600 Ω) | Within 105 mV of rails at 1.8 V - delivers >94% of supply headroom for maximum dynamic range into standard ADC reference voltages. |
| Input Common-Mode Range | V− − 0.2 V to V+ + 0.2 V (25°C) - accepts ground-referenced or slightly negative inputs in single-supply configurations, simplifying transducer interfacing. |
| Operating Temperature | −40°C to +125°C - qualified for automotive cabin modules, industrial IoT nodes, and medical devices requiring extended thermal robustness. |
Pinout & Package
LMV932MA/NOPB is packaged in an 8-pin VSSOP (DGK) with nominal body size 3.00 mm × 3.00 mm, offering high thermal performance (RθJA = 184.5°C/W) and compatibility with fine-pitch PCB assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage input; rail-to-rail capable with 45-mA short-circuit current limit. |
| 2 | −IN A | Inverting input for channel A - forms feedback node in inverting configurations; high-impedance CMOS input (IB ≤ 50 nA). |
| 3 | +IN A | Noninverting input for channel A - accepts signals from sensors, references, or DACs across full rail-to-rail common-mode range. |
| 4 | V− | Negative supply terminal - connects to GND in single-supply use; supports split-rail operation down to −0.3 V. |
| 5 | V+ | Positive supply terminal - accepts 1.8–5.5 V; decoupling capacitor required within 1 cm for stability. |
| 6 | −IN B | Inverting input for channel B - electrically isolated from channel A; enables dual-signal processing without crosstalk (123 dB isolation). |
| 7 | OUT B | Amplifier B output - independent output stage; can drive separate loads or form composite filter topologies with channel A. |
| 8 | +IN B | Noninverting input for channel B - identical electrical specs to +IN A; supports differential pair or dual-sensor readout. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input extends 200 mV beyond supplies; output swings to within 30 mV of rails (2-kΩ load) - eliminates need for level shifters in low-voltage systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-I/SN | Higher 10-μA input bias current (vs. 50-nA max for LMV932MA/NOPB); 10-MHz GBW but 600-μA supply current. | Better for higher-speed AC-coupled audio; less suitable for high-impedance pH or thermocouple sensors due to IB. | Choose MCP6022-I/SN when bandwidth >5 MHz is required and power budget allows ≥1.2 mA total. |
| TSV912IDT | Lower 1.1-mV max VOS and 5.5-V/μs slew rate, but only specified down to 2.7 V supply - not functional at 1.8 V. | Preferred for 3.3-V systems needing tighter DC accuracy; cannot replace LMV932MA/NOPB in 1.8-V or single-cell Li-ion designs. | Select TSV912IDT only for 2.7–5.5-V applications where offset-critical DC performance outweighs ultra-low-voltage operation. |
Compared with MCP6022-I/SN and TSV912IDT, LMV932MA/NOPB uniquely supports 1.8-V operation with rail-to-rail I/O and sub-200-μA total supply current - making it the sole viable option for coin-cell or energy-harvesting sensor nodes requiring both ultra-low voltage and precision.

FAQ
What is the minimum supply voltage for reliable operation of the LMV932MA/NOPB?
The LMV932MA/NOPB is fully specified and guaranteed to operate from 1.8 V to 5.5 V. At 1.8 V, it delivers 1.4-MHz gain bandwidth, rail-to-rail I/O, and 103–205 μA per-channel supply current - making LMV932MA/NOPB ideal for single-cell Li-ion (2.7–4.2 V) and two-cell alkaline (2.4–3.2 V) systems where headroom is constrained.
Does the LMV932MA/NOPB support rail-to-rail input common-mode voltage?
Yes. The LMV932MA/NOPB features rail-to-rail input with common-mode range extending 200 mV beyond the supply rails (V− − 0.2 V to V+ + 0.2 V at 25°C). This allows direct interfacing with ground-referenced sensors or signals slightly below V− - a capability confirmed in the DC Electrical Characteristics table for all supply voltages (1.8 V, 2.7 V, 5 V).
Can the LMV932MA/NOPB drive a 1000-pF capacitive load stably?
Yes. The LMV932MA/NOPB is characterized to drive up to 1000-pF capacitive loads with minimal ringing, as stated in the device description and verified in typical application circuits. This enables direct connection to ADC input capacitors, long PCB traces, or LCD bias networks without requiring isolation resistors or external compensation.
What is the maximum input offset voltage specification for LMV932MA/NOPB across temperature?
The LMV932MA/NOPB has a maximum input offset voltage of 7.5 mV across the full operating temperature range (−40°C to +125°C) at 1.8 V supply, per the DC Electrical Characteristics table. At 25°C, the limit is tighter: 5.5 mV max. This ensures predictable DC error in precision sensor interfaces without trimming.
Which package variants are available for the LMV932MA/NOPB?
The LMV932MA/NOPB is offered exclusively in the 8-pin VSSOP (DGK) package with 3.00 mm × 3.00 mm body size and 0.5-mm lead pitch. It is not available in SOIC (D) or other footprints - this is explicitly confirmed in TI's orderable addendum and mechanical drawings for the LMV932-N family.
