Product details
Overview
LMV932Q1MAX/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 rail-to-rail output swing within 105 mV of either rail under 600-Ω load - enabling precision signal conditioning in engine control units and battery management systems.
For engineers reviewing the LMV932Q1MAX/NOPB datasheet, LMV932Q1MAX/NOPB pinout, LMV932Q1MAX/NOPB application, or LMV932Q1MAX/NOPB equivalent, key selection criteria include its −40°C to +125°C operating range, 200-mV beyond-rail input common-mode capability, ultra-low power consumption at 1.8 V, and SOIC-8 packaging suitable for space-constrained automotive PCBs.
Technical Context
The LMV932Q1MAX/NOPB implements a complementary PNP/NPN input stage to achieve rail-to-rail input common-mode range extending 200 mV beyond both supply rails. Its output stage uses a Class AB architecture capable of sourcing/sinking up to 30 mA (at 2.7 V) while maintaining stability driving ≥600-Ω loads and ≤1000-pF capacitive loads.
This dual op-amp operates across 1.8 V to 5.5 V single-supply or split-supply configurations. It features 101-dB open-loop DC gain, 70° phase margin, and 7.5-dB gain margin at 1.8 V - ensuring robust closed-loop performance in low-frequency sensor interfaces and active filters without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - supports direct integration into single-cell Li-ion (3.0–3.7 V), two-cell alkaline (2.4–3.2 V), and 5-V automotive domains. |
| 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 ultrasonic transducer signal conditioning. |
| Input Offset Voltage (max) | 4 mV at 25°C - ensures ≤0.4% error in 1-V full-scale analog front-ends used in occupant detection or BMS cell voltage monitoring. |
| Supply Current (per channel) | 103–205 μA - allows continuous operation in always-on vehicle subsystems with sub-500-μA total quiescent budget. |
| Output Swing (600 Ω load) | Within 105 mV of rails at 1.8 V - preserves >94% dynamic range for ADC drivers interfacing 12-bit SAR converters. |
| Input Common-Mode Range | V− − 0.2 V to V+ + 0.2 V - permits direct sensing of signals below ground or above supply, e.g., shunt-based high-side current measurement. |
| CMRR / PSRR | ≥55 dB / ≥70 dB over full temperature range - rejects supply ripple and common-mode noise in noisy engine bay environments. |
Pinout & Package
LMV932Q1MAX/NOPB is housed in an 8-pin SOIC package (4.90 mm × 3.91 mm body size) with standard surface-mount footprint and thermal performance (RθJA = 125.9°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT A (Pin 1) | Amplifier A output | Delivers rail-to-rail buffered or amplified signal; drives 600-Ω loads with <105-mV headroom at 1.8 V. |
| −IN A (Pin 2) | Inverting input, Channel A | Accepts feedback network for inverting configurations; matched bias current minimizes offset in precision integrators. |
| +IN A (Pin 3) | Noninverting input, Channel A | Supports beyond-rail sensing down to V− − 0.2 V - critical for single-supply high-side current sense amps. |
| V− (Pin 4) | Negative supply | Reference for single-supply (GND) or negative rail in split-supply; must be decoupled locally with 0.1-μF ceramic capacitor. |
| V+ (Pin 8) | Positive supply | Accepts 1.8–5.5 V; internal regulation ensures consistent GBW and slew rate across voltage range. |
| +IN B (Pin 5) | Noninverting input, Channel B | Independent input for second signal path; enables dual-sensor differential measurement without cross-talk. |
| −IN B (Pin 6) | Inverting input, Channel B | Configurable for independent gain-setting; amplifier-to-amplifier isolation >123 dB prevents crosstalk in multi-channel BMS monitoring. |
| OUT B (Pin 7) | Amplifier B output | Electrically isolated output stage; supports simultaneous drive of separate loads (e.g., heater control + sensor interface). |
Key Features

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV932QDRQ1 | Same electrical specs and AEC-Q100 Grade 1 qualification; differs only in tape-and-reel packaging (no NOPB suffix) and RoHS exemption status. | No functional difference; identical use in ECU, BCM, and BMS designs requiring automotive-grade dual op-amps. | Select LMV932QDRQ1 for automated SMT assembly where reel packaging is required; LMV932Q1MAX/NOPB preferred for prototyping or small-batch builds. |
| MCP6022-E/SN | Higher 10-μA input bias current vs. LMV932Q1MAX/NOPB's 15–50 nA; 10-MHz GBW but 600-μA supply current per channel. | Suitable for non-automotive industrial applications where higher speed and lower precision offset (2.5 mV max) are acceptable trade-offs for increased power. | Choose MCP6022-E/SN only when >1-MHz bandwidth is mandatory and 125°C operation or AEC-Q100 compliance is not required. |

What is the typical supply current per channel for LMV932Q1MAX/NOPB at 1.8 V?
The typical supply current per channel for LMV932Q1MAX/NOPB is 103 μA at 1.8 V and 25°C, with a maximum of 205 μA over the full −40°C to +125°C temperature range. This ultra-low quiescent current enables continuous operation in always-on vehicle subsystems while maintaining 1.4-MHz gain-bandwidth product.
Can LMV932Q1MAX/NOPB drive a 1000-pF capacitive load?
Yes, LMV932Q1MAX/NOPB is characterized to drive up to 1000-pF capacitive loads with minimal ringing and no external compensation. This capability is confirmed in the datasheet's "Application and Implementation" section and enables stable operation into long PCB traces, EMI filter networks, or ADC input capacitance without added series resistance.
Is LMV932Q1MAX/NOPB pin-compatible with other devices in the LMV93x-N-Q1 family?
