Product details
Overview
LMV932QDRQ1 from Texas Instruments is a dual-channel automotive-grade operational amplifier with rail-to-rail input and output, 1.4 MHz gain bandwidth, 100 µA per channel supply current, and operation down to 1.8 V. It delivers 80 mV from rails into 600 Ω at 1.8 V and supports –40°C to 125°C ambient for battery-powered sensor signal conditioning in automotive body control modules.
For engineers reviewing the LMV932QDRQ1 datasheet, LMV932QDRQ1 pinout, LMV932QDRQ1 application, or LMV932QDRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, rail-to-rail common-mode range extending 200 mV beyond supplies, low 4 mV max input offset voltage, and SOIC-8 packaging suitable for space-constrained automotive PCB layouts.
Technical Context
The LMV932QDRQ1 employs a Class AB output stage with complementary P/N transistor pairs enabling true rail-to-rail output swing. Its input stage uses an NMOS differential pair with extended common-mode range (VCC– – 0.2 V to VCC+ + 0.2 V), allowing operation with inputs 200 mV beyond either supply rail.
It features internal frequency compensation optimized for unity-gain stability with capacitive loads up to 1000 pF and maintains ≥67° phase margin across 1.8–5 V supply range. The device achieves 101 dB open-loop DC gain and 1.4 MHz GBW while consuming only 103 µA per channel at 1.8 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5 V single-supply - enables direct interface with Li-ion or two-cell alkaline batteries without level-shifting. |
| Gain Bandwidth Product | 1.4 MHz - supports stable closed-loop gain up to ~100× at audio and low-speed sensor frequencies. |
| Input Offset Voltage (max) | 4 mV - ensures ≤4 mV error in precision DC-coupled amplification of thermistor or bridge sensor outputs. |
| Supply Current (per channel) | 100 µA - allows continuous operation in always-on automotive modules with sub-200 µA total quiescent draw. |
| Output Swing (600 Ω load) | 80 mV from rails at 1.8 V - preserves >95% dynamic range for 12-bit ADC interfacing in low-voltage systems. |
| Common-Mode Input Range | VCC– – 0.2 V to VCC+ + 0.2 V - accepts signals below ground or above VCC, critical for single-supply transducer biasing. |
| Operating Temperature | –40°C to 125°C - qualified per AEC-Q100 Grade 1 for under-hood and cabin electronics deployment. |
Pinout & Package
LMV932QDRQ1 is housed in an 8-pin SOIC (D package) with standard pinout compatible with industry-wide footprint libraries. Pin 1 is marked by a beveled corner or dot; the device uses conventional dual-opamp topology with independent input and output terminals per channel.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Channel 1 output - drives downstream ADC input or active filter stage with rail-to-rail capability. |
| 2 | IN−1 | Inverting input for Channel 1 - connects to feedback network or sensor reference point in inverting configurations. |
| 3 | IN+1 | Non-inverting input for Channel 1 - interfaces directly with high-impedance sensors (e.g., thermocouples, pH electrodes). |
| 4 | VCC− | Negative supply rail (GND in single-supply) - must be low-impedance with local 100 nF ceramic decoupling. |
| 5 | VCC+ | Positive supply rail - accepts 1.8–5 V; requires separate 100 nF decoupling adjacent to pin. |
| 6 | IN+2 | Non-inverting input for Channel 2 - enables dual-sensor monitoring (e.g., temperature + voltage) on one IC. |
| 7 | IN−2 | Inverting input for Channel 2 - used for differential sensing or programmable gain stage configuration. |
| 8 | OUT2 | Channel 2 output - provides independent signal path for redundancy or multi-function analog front-end design. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 80 mV of VCC+/VCC− into 600 Ω at 1.8 V, maximizing usable ADC input range without external level-shifting. |
| Extended input common-mode range | Accepts signals 200 mV beyond supply rails, enabling direct connection to grounded or floating transducers without bias resistors. |
| AEC-Q100 Grade 1 qualification | Validated for automotive use from –40°C to 125°C ambient, including thermal cycling, ESD (2 kV HBM), and board-level reliability testing. |
| Low 100 µA/channel quiescent current | Supports always-on battery monitoring circuits with <200 µA total system current, extending vehicle battery life during sleep mode. |
| Stable with capacitive loads up to 1000 pF | Eliminates need for isolation resistors when driving long traces or ADC input capacitance, simplifying layout and reducing BOM count. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV932DR | Non-automotive version; not AEC-Q100 qualified; identical electrical specs and SOIC-8 package. | Not suitable for production automotive ECUs; acceptable for prototyping or industrial designs requiring same performance. | Select LMV932DR only for non-automotive applications where AEC-Q100 compliance is unnecessary. |
| MCP6022-E/SN | Microchip part; 10 µA lower supply current (90 µA/ch), but 1 MHz GBW and 1.5 mV VIO max - lower bandwidth and higher offset than LMV932QDRQ1. | Better for ultra-low-power battery devices where bandwidth <1 MHz suffices; less suitable for precision sensor conditioning requiring <4 mV offset. | Choose MCP6022-E/SN when power budget is tighter than 100 µA/ch and 1 MHz GBW meets signal chain requirements. |
Compared with LMV932DR and MCP6022-E/SN, the LMV932QDRQ1 uniquely combines AEC-Q100 qualification, 1.4 MHz bandwidth, and 4 mV max VIO in SOIC-8 - making it the only option qualified for safety-critical automotive signal paths demanding both precision and reliability.

FAQ
What is the maximum operating temperature range for the LMV932QDRQ1?
The LMV932QDRQ1 is specified for operation from –40°C to +125°C ambient temperature and is AEC-Q100 Grade 1 qualified. This rating covers under-hood and cabin environments in automotive applications. Thermal derating is not required within this range, and the device maintains full electrical specifications across the entire span, including input offset voltage, gain bandwidth, and output drive capability.
Does the LMV932QDRQ1 support single-supply operation at 1.8 V?
Yes, the LMV932QDRQ1 is fully specified for 1.8 V single-supply operation. At this voltage, it delivers 1.4 MHz gain bandwidth, 103 µA per channel supply current, rail-to-rail output swing (80 mV from rails into 600 Ω), and 200 mV beyond-rail input common-mode range. These parameters are validated per the SLOS462C datasheet across –40°C to 125°C, confirming suitability for ultra-low-voltage battery-powered automotive subsystems.
Is the LMV932QDRQ1 pin-compatible with standard LMV932 variants?
Yes, the LMV932QDRQ1 uses the same SOIC-8 (D package) footprint and pinout as the commercial LMV932DR. Pin assignments - OUT1, IN−1, IN+1, VCC−, VCC+, IN+2, IN−2, OUT2 - are identical. No PCB layout changes are needed when upgrading from LMV932DR to LMV932QDRQ1, though system-level validation for automotive qualification remains necessary.
What is the typical input bias current of the LMV932QDRQ1 at 25°C?
The typical input bias current of the LMV932QDRQ1 is 15 nA at 25°C and 1.8 V supply, with a maximum of 75 nA across the full temperature and voltage range. This low bias current minimizes voltage errors in high-impedance sensor interfaces (e.g., pH electrodes or photodiode transimpedance stages) and reduces loading effects on RC filter networks in precision analog front-ends.
Can the LMV932QDRQ1 drive a 600 Ω load while maintaining rail-to-rail output swing?
Yes, the LMV932QDRQ1 is characterized to deliver rail-to-rail output swing into a 600 Ω load. At 1.8 V supply, the output reaches within 80 mV of both VCC+ and VCC−; at 5 V, it achieves within 160 mV. This capability is maintained across –40°C to 125°C and enables direct interfacing with legacy ADCs and analog switches without external level-shifting circuitry.
