Product details
Overview
LMV932Q1MA/NOPB from Texas Instruments is an AEC-Q100 Grade 1 qualified dual rail-to-rail input/output operational amplifier optimized for 1.8-V operation in automotive systems. It delivers 1.4-MHz gain-bandwidth product, 100-μA per-channel supply current, 4-mV max input offset voltage, and output swing within 105 mV of rails under 600-Ω load - enabling precision signal conditioning in engine control units and battery management systems.
For engineers reviewing the LMV932Q1MA/NOPB datasheet, LMV932Q1MA/NOPB pinout, LMV932Q1MA/NOPB application, or LMV932Q1MA/NOPB equivalent, key selection criteria include its −40°C to +125°C operating range, rail-to-rail input extending 200 mV beyond supplies, 75-dB min CMRR at 1.8 V, and SOIC-8 packaging validated for space-constrained automotive PCBs.
Technical Context
The LMV932Q1MA/NOPB implements a complementary PNP/NPN input stage enabling rail-to-rail common-mode input range (V− −0.2 V to V+ +0.2 V) with seamless transition near V+ −1 V. Its unity-gain-stable architecture supports capacitive loads up to 1000 pF with minimal ringing, and its high DC open-loop gain (101 dB typical) ensures accurate low-frequency amplification in sensor front-ends.
It operates across 1.8-V to 5.5-V single-supply or split-supply configurations, with specified performance at 1.8 V, 2.7 V, and 5 V. Input bias current remains below 35 nA (25°C), and amplifier-to-amplifier isolation exceeds 123 dB - critical for dual-channel independence in multi-sensor automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - enables direct interface with Li-ion single-cell (3.0–4.2 V) and two-cell (6.0–8.4 V) battery systems via LDO regulation. |
| Gain-Bandwidth Product | 1.4 MHz - supports stable closed-loop gain ≥10 up to ~140 kHz for ultrasonic transducer signal conditioning. |
| Input Offset Voltage (max) | 4 mV at 25°C - limits DC error to ≤0.4% of full-scale in 1-V reference-based BMS voltage monitoring. |
| Output Swing (600 Ω) | Within 105 mV of rails at 1.8 V - preserves >94% dynamic range for 0–1.8 V ADC inputs without level-shifting. |
| Supply Current (per channel) | 103–205 μA - allows dual-channel operation at <410 μA total, suitable for always-on vehicle subsystems. |
| Common-Mode Range | V− −0.2 V to V+ +0.2 V - permits sensing signals below ground (e.g., shunt-based current measurement) and above supply. |
| Operating Temperature | −40°C to +125°C ambient - meets AEC-Q100 Grade 1 requirements for under-hood ECU placement. |
Pinout & Package
LMV932Q1MA/NOPB is housed in an 8-pin SOIC package (4.90 mm × 3.91 mm body size), optimized for thermal performance (RθJA = 125.9°C/W) and automated assembly in automotive production.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT A (Pin 1) | Amplifier A output | Drives downstream circuitry; rail-to-rail swing supports direct connection to SAR ADC reference buffers. |
| −IN A (Pin 2) | Inverting input, Channel A | Accepts feedback network for inverting configurations; high impedance (>100 GΩ) minimizes loading on sensor sources. |
| +IN A (Pin 3) | Noninverting input, Channel A | Connects to high-impedance sensors (e.g., thermistors); extended CMVR enables biasing outside supply rails. |
| V− (Pin 4) | Negative supply | Ground reference in single-supply mode; supports true split-supply operation down to −0.3 V. |
| V+ (Pin 8) | Positive supply | Accepts 1.8–5.5 V; internal ESD protection rated to ±2000 V HBM ensures robustness in manufacturing and field environments. |
| +IN B (Pin 5) | Noninverting input, Channel B | Independent input for second sensor path; >123 dB inter-channel isolation prevents crosstalk in dual-signal acquisition. |
| −IN B (Pin 6) | Inverting input, Channel B | Configurable for differential sensing or active filtering; matched input characteristics ensure channel-to-channel tracking. |
| OUT B (Pin 7) | Amplifier B output | Electrically isolated output; supports independent gain/offset calibration per channel in safety-critical diagnostics. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV912IQDRQ1 | Higher 8-MHz GBW but 150-μA per-channel supply current; 1.1-mV typical VOS vs. 4-mV max for LMV932Q1MA/NOPB. | Better for higher-frequency sensor interfaces (e.g., radar IF stages); less optimal for ultra-low-power always-on BMS monitoring. | Select TSV912IQDRQ1 when bandwidth >2 MHz is required and supply current budget allows +50% increase per channel. |
| MCP6022-E/SN | Wider 1.8–5.5 V range same; 17-μA per-channel supply current but only 1-MHz GBW and no AEC-Q100 qualification. | Suitable for cost-sensitive non-automotive industrial controls; lacks automotive reliability validation and high-temp performance. | Choose MCP6022-E/SN for commercial-grade applications where AEC-Q100 compliance and 125°C operation are not required. |
Compared with TSV912IQDRQ1 and MCP6022-E/SN, LMV932Q1MA/NOPB uniquely balances AEC-Q100 Grade 1 qualification, 1.4-MHz bandwidth, and sub-105-μA supply current - making it the only option qualified for safety-critical automotive signal chains requiring both precision and low power at 125°C.

FAQ
What is the maximum operating temperature for LMV932Q1MA/NOPB?
The LMV932Q1MA/NOPB is rated for ambient operating temperatures from −40°C to +125°C, meeting AEC-Q100 Grade 1 requirements for under-hood automotive applications. This specification is validated across all electrical parameters in the datasheet, including input offset voltage drift, gain-bandwidth product, and output swing performance.
Does LMV932Q1MA/NOPB support single-supply operation?
Yes, LMV932Q1MA/NOPB fully supports single-supply operation from 1.8 V to 5.5 V. Its rail-to-rail input extends 200 mV beyond both supply rails (V− −0.2 V to V+ +0.2 V), and its rail-to-rail output swings within 105 mV of each rail under 600-Ω load at 1.8 V - enabling direct interfacing with unipolar sensor signals and ADCs.
What is the input offset voltage specification for LMV932Q1MA/NOPB?
The LMV932Q1MA/NOPB has a maximum input offset voltage of 4 mV at 25°C and 6 mV across the full −40°C to +125°C temperature range. Typical VOS is 1 mV at 25°C, with average drift of 5.5 μV/°C - critical for maintaining accuracy in precision voltage monitoring circuits like BMS cell balancing.
Is LMV932Q1MA/NOPB pin-compatible with other devices in the LMV93x-N-Q1 family?
No - LMV932Q1MA/NOPB uses an 8-pin SOIC package with dedicated dual-channel pinout (Pins 1–8), while LMV931-N-Q1 is in 5-pin SOT-23/SC-70 and LMV934-N-Q1 is in 14-pin TSSOP. Pin functions are consistent across the family (e.g., +IN A/B, −IN A/B, OUT A/B, V+, V−), but physical pin count and layout differ; PCB redesign is required for substitution.
What load capacitance can LMV932Q1MA/NOPB drive stably?
LMV932Q1MA/NOPB is characterized to drive up to 1000 pF capacitive loads with minimal ringing, as confirmed in the datasheet's "Typical Characteristics" section. This capability eliminates the need for series isolation resistors when interfacing with ADC input capacitance or long PCB traces - simplifying layout and preserving signal integrity in automotive sensor nodes.
