Texas Instruments LMV358QPWR

Overview

LMV358QPWR from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 5.5 V) single-supply operation, delivering 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 210 μA typical supply current per amplifier - used in portable media players, HVAC sensor conditioning, and motor control feedback loops.

For engineers reviewing the LMV358QPWR datasheet, LMV358QPWR pinout, LMV358QPWR application, or LMV358QPWR equivalent, key selection criteria include rail-to-rail output swing down to 60 mV from rails at 10 kΩ load, input offset voltage of 7 mV max at 25°C, –40°C to 125°C operating temperature range, and compatibility with space-constrained TSSOP-8 packaging.

Technical Context

The LMV358QPWR implements a CMOS-input, rail-to-rail output op-amp architecture with common-mode input voltage range extending to ground, enabling direct interfacing with single-ended sensors and ADCs. Its internal biasing supports stable operation across 2.7 V–5.5 V supply rails without external level-shifting.

It features no crossover distortion due to complementary output stage design, maintains ≥50 dB CMRR over 0–1.7 V common-mode range at 2.7 V supply, and achieves 60° phase margin into 2 kΩ resistive loads - ensuring robust stability in unity-gain buffer and active filter configurations.

FAQ

What is the maximum supply voltage for LMV358QPWR?

The absolute maximum supply voltage for LMV358QPWR is 5.5 V, as specified in Section 7.1 Absolute Maximum Ratings of the TI datasheet SLOS263W. Operation above this voltage risks permanent damage. Recommended operating range is 2.7 V to 5.5 V, with full electrical performance guaranteed across that span at temperatures from –40°C to 125°C.

Does LMV358QPWR support true rail-to-rail input?

No, LMV358QPWR does not support rail-to-rail input. Its common-mode input voltage range extends to ground (0 V) but only up to VCC – 0.2 V at 2.7 V supply, per Section 7.5 Electrical Characteristics. It is a rail-to-rail *output* amplifier - output swings within 60 mV of VCC+ and 140 mV of GND under 10 kΩ load - but input cannot reach the positive rail.

Can LMV358QPWR drive a 600 Ω load?

LMV358QPWR can source up to 60 mA and sink up to 160 mA (Section 7.6), but driving a continuous 600 Ω load at ±2.5 V output swing requires ~4.2 mA - well within its capability. However, Figure 24 shows reduced output swing (to ~±2.2 V) at 600 Ω due to output stage compliance limits; for full rail-to-rail performance, maintain RL ≥ 2 kΩ.

Is LMV358QPWR pin-compatible with LM358?

No, LMV358QPWR is not pin-compatible with standard LM358. While both are dual op-amps, LM358 uses SOIC-8 or PDIP-8 with pin 1 = OUT A, 2 = IN– A, 3 = IN+ A, 4 = GND, 5 = IN+ B, 6 = IN– B, 7 = OUT B, 8 = VCC+. LMV358QPWR TSSOP-8 follows TI's modern dual-op-amp pinout: 1 = OUT A, 2 = IN– A, 3 = IN+ A, 4 = GND, 5 = VCC+, 6 = OUT B, 7 = IN– B, 8 = IN+ B - swapping VCC+ and OUT B positions.

What is the typical input bias current of LMV358QPWR?

The typical input bias current of LMV358QPWR is 15 nA at 25°C and 2.7 V supply (Section 7.5), rising to 500 nA maximum across the full –40°C to 125°C temperature range (Section 7.6). This CMOS-input characteristic enables high-impedance sensor interfaces (e.g., pH electrodes, photodiode transimpedance) without significant DC error from bias current flow.
