Texas Instruments LMV358AQDRQ1

Overview

LMV358AQDRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 qualified automotive operational amplifier with rail-to-rail output, ±1 mV input offset voltage, 1 MHz unity-gain bandwidth, and 70 µA per channel quiescent current. It operates from 2.5 V to 5.5 V supply and delivers 20 mV rail-to-rail output swing into 10 kΩ at 5.5 V - enabling precision low-side current sensing in HEV/EV motor control and ADAS powertrain sensor interfaces.

For engineers reviewing the LMV358AQDRQ1 datasheet, LMV358AQDRQ1 pinout, LMV358AQDRQ1 application, or LMV358AQDRQ1 equivalent, key selection criteria include its AEC-Q100 qualification, resistive open-loop output impedance (1200 Ω), 500 pF capacitive-load drive capability, EMI/RFI filtering, and no-phase-reversal behavior under overdrive - all critical for robust operation in infotainment, body electronics, and safety-critical automotive subsystems.

Technical Context

The LMV358AQDRQ1 implements a P-channel/N-channel parallel input stage to extend common-mode range to within 100 mV of V– and avoid phase reversal, while its class-AB output stage enables true rail-to-rail swing. Its resistive open-loop output impedance simplifies stability with high capacitive loads up to 500 pF without external compensation.

This dual op amp is unity-gain stable and features integrated RFI/EMI rejection filtering, 30 nV/√Hz input voltage noise at 10 kHz, and 76° phase margin at G = 1 with 10 pF load - supporting reliable signal conditioning in noisy automotive environments across –40°C to +125°C.

FAQ

What automotive qualification level does LMV358AQDRQ1 meet?

LMV358AQDRQ1 is AEC-Q100 qualified to Grade 1, covering operation from –40°C to +125°C ambient temperature. It meets HBM ESD Level 2 (±2 kV) and CDM Level C6 (±1 kV), and is approved for use in infotainment, body electronics, passive safety, and ADAS subsystems - including powertrain current sensing where specified.

Does LMV358AQDRQ1 support true rail-to-rail input and output?

LMV358AQDRQ1 provides rail-to-rail output swing (within 20 mV of rails into 10 kΩ at 5.5 V) and rail-to-rail input common-mode range extending 100 mV below V− and within 1 V of V+. While the input does not reach full V+ rail, its extended range supports most single-supply applications including low-side current sensing and sensor buffering without external level shifting.

What is the maximum capacitive load LMV358AQDRQ1 can drive stably?

LMV358AQDRQ1 is characterized for stable operation with up to 500 pF capacitive load without external compensation, thanks to its resistive open-loop output impedance. This enables direct connection to ADC input capacitance, long PCB traces, or display driver inputs - eliminating series isolation resistors typically needed with conventional op amps.

How does LMV358AQDRQ1 handle overdrive conditions without phase reversal?

LMV358AQDRQ1 incorporates a parallel P-channel/N-channel input stage that prevents phase reversal during overdrive. When input voltages exceed the common-mode range, the complementary structure maintains correct polarity at the output - a critical feature for motor control and safety-critical feedback loops where erroneous inversion could cause system faults.

Can LMV358AQDRQ1 operate from a 3.3 V supply in automotive systems?

Yes, LMV358AQDRQ1 is fully specified for operation from 2.5 V to 5.5 V, including standard 3.3 V automotive domains. At 3.3 V, it maintains ±1 mV offset, 1 MHz bandwidth, and rail-to-rail output swing within 35 mV of rails into 10 kΩ - making it ideal for 3.3 V microcontroller I/O interfacing, CAN transceiver biasing, and low-voltage sensor signal conditioning.
