Texas Instruments LMV358AIDR

Overview

LMV358AIDR from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier optimized for low-voltage (2.5 V to 5.5 V) single-supply operation, featuring ±1 mV input offset voltage, 1 MHz unity-gain bandwidth, 70 µA per channel quiescent current, and –40°C to 125°C operating temperature range - deployed in smoke detectors, wearable devices, and low-side current sensing circuits.

For engineers reviewing the LMV358AIDR datasheet, LMV358AIDR pinout, LMV358AIDR application, or LMV358AIDR equivalent, key selection criteria include capacitive-load drive capability (500 pF), resistive open-loop output impedance (1.2 kΩ at 1 MHz), rail-to-rail output swing within 20 mV of rails (at 10 kΩ), EMI/RFI filtering, and no-phase-reversal behavior under overdrive.

Technical Context

The LMV358AIDR implements a P-channel/N-channel parallel input stage enabling rail-to-rail input common-mode range (V– – 0.1 V to V+ – 1 V) and eliminating phase reversal, while its Class-AB output stage delivers full rail-to-rail swing with low output impedance. Its resistive open-loop output impedance simplifies stability with high capacitive loads.

Designed for unity-gain stability and low-noise (30 nV/√Hz at 10 kHz), the device supports single-supply signal conditioning where dynamic range preservation is critical - such as driving SAR ADC inputs or amplifying photodiode currents in 3.3 V systems.

Key Specifications

FAQ

What is the maximum capacitive load the LMV358AIDR can drive without oscillation?

The LMV358AIDR is characterized to drive up to 500 pF capacitive load stably in unity-gain configuration, thanks to its resistive open-loop output impedance. This eliminates need for external series resistance in typical ADC buffer or cable-driving applications. For loads >500 pF, phase margin degrades gradually - verify stability with actual layout and load in final design. LMV358AIDR's 76° phase margin at 1 MHz ensures robustness even near limit.

Does the LMV358AIDR support true rail-to-rail input?

LMV358AIDR features rail-to-rail *output*, but its input common-mode range extends from V– – 0.1 V to V+ – 1 V - not full rail-to-rail input. The P-channel input stage enables negative-rail operation, while the parallel N-channel stage prevents phase reversal. For full rail-to-rail input, consider TI's TLV9002; LMV358AIDR remains ideal for single-supply applications where V– = GND and signals stay ≥0.1 V above ground.

Can the LMV358AIDR operate from a 2.5 V single supply?

Yes - LMV358AIDR is fully specified from 2.5 V to 5.5 V supply. At 2.5 V, it maintains ±1 mV typical offset, 70 µA/channel quiescent current, and rail-to-rail output swing within 50 mV of rails (at 2 kΩ load). All key parameters including GBW (1 MHz), PSRR (78 dB), and CMRR (86 dB) remain valid across this range, making LMV358AIDR suitable for deeply discharged Li-ion or coin-cell systems.

What is the overload recovery time of the LMV358AIDR?

The LMV358AIDR recovers from output saturation in approximately 850 ns - measured from 90% of final value after large overdrive step. This fast recovery enables accurate pulse-amplitude measurement in transient-sensing applications like motion detection or current spike monitoring. Recovery time is consistent across –40°C to 125°C and independent of supply voltage between 2.5 V and 5.5 V.

Is the LMV358AIDR pin-compatible with legacy LMV358 variants?

LMV358AIDR uses the standard SOIC-8 (D) footprint and shares identical pinout with LMV358IDR, LMV358M, and LMV358IPW. However, internal enhancements - including EMI filtering, tighter offset (±1 mV vs ±3 mV), and improved capacitive-load drive - mean LMV358AIDR is a functional upgrade, not a drop-in replacement where EMI or precision is critical. Always validate noise and stability in target application.
