Texas Instruments LMV358IPW

Overview

LMV358IPW from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage single-supply operation (2.7 V to 5.5 V), delivering 1 MHz unity-gain bandwidth, 1 V/μs slew rate, and 210 μA typical supply current per amplifier - used in portable audio signal conditioning, sensor front-end buffering, and power supply feedback loops.

For engineers reviewing the LMV358IPW datasheet, LMV358IPW pinout, LMV358IPW application, or LMV358IPW 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 LMV358IPW 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 compensation ensures stable unity-gain operation with capacitive loads up to 100 pF.

It operates as a dual-channel device with independent amplifiers sharing only the VCC+ and GND pins; no shutdown control is present (unlike LMV324S), and both channels remain active whenever powered. Input bias current is 250 nA max at 25°C, supporting high-impedance source applications.

FAQ

What is the maximum supply voltage for LMV358IPW?

The absolute maximum supply voltage for LMV358IPW is 5.5 V, as specified in the Absolute Maximum Ratings table. Operation above this voltage risks permanent damage. Recommended operating range is 2.7 V to 5.5 V, with full parametric performance guaranteed across that span - including rail-to-rail output swing and 1 MHz bandwidth. Exceeding 5.5 V voids warranty and may trigger internal ESD clamp conduction.

Does LMV358IPW support dual-supply operation?

Yes, LMV358IPW supports dual-supply operation with VCC+ and GND referenced to split rails (e.g., ±2.5 V), though its design emphasis is single-supply use from 2.7 V to 5.5 V. In dual-supply mode, the input common-mode range extends from –0.2 V to VCC+ – 0.2 V, and output swing remains rail-to-rail relative to the chosen supply rails. No external level-shifting is needed.

What is the input common-mode voltage range of LMV358IPW?

The input common-mode voltage range of LMV358IPW is 0 V to VCC+ – 1.2 V at 25°C (with CMRR ≥50 dB), meaning it includes ground (0 V) and extends up to 1.2 V below the positive rail. This allows direct interfacing with sensors and ADCs referenced to system GND - a key advantage over older op-amps like LM358, which require input biasing above GND.

Can LMV358IPW drive capacitive loads?

LMV358IPW is stable driving capacitive loads up to 100 pF with 10 kΩ series resistance, as confirmed by phase margin measurements ≥60° in the datasheet. For loads >100 pF, external isolation resistance (≥100 Ω) or output RC filtering is recommended to prevent peaking or oscillation. The device's internal compensation avoids need for external compensation components in most standard configurations.

Is LMV358IPW pin-compatible with LM358?

No, LMV358IPW is not pin-compatible with LM358. While both are dual op-amps, LM358 uses an 8-pin DIP or SOIC package with pinout: 1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+. LMV358IPW (TSSOP-8) uses: 1OUT, 1IN–, 1IN+, GND, VCC+, 2OUT, 2IN–, 2IN+. The GND/VCC– and VCC+/VCC+ assignments differ, and swapping packages requires PCB layout revision.
