Texas Instruments LMV358IPWRG4

Overview

LMV358IPWRG4 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. It features rail-to-rail output swing, ground-sensing input range, and operates across –40°C to 125°C - used in portable media players, HVAC sensor conditioning, and motor control feedback loops.

For engineers reviewing the LMV358IPWRG4 datasheet, LMV358IPWRG4 pinout, LMV358IPWRG4 application, or LMV358IPWRG4 equivalent, key selection criteria include its dual-channel rail-to-rail output capability, low quiescent current at 2.7 V, guaranteed operation over automotive temperature range, and compatibility with space-constrained TSSOP-8 layouts.

Technical Context

The LMV358IPWRG4 implements a CMOS-input stage enabling rail-to-rail output swing while maintaining input common-mode range extending to ground. Its internal architecture supports stable unity-gain operation with 60° phase margin and 10 dB gain margin at 5 V supply into 2 kΩ load.

It operates as a true single-supply op-amp: no shutdown pin (unlike LMV324S), no internal reference, and no channel enable logic - both amplifiers are always active when powered. Input bias current remains below 250 nA across full temperature range.

Supply support for LMV358IPWRG4 includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Texas Instruments is a global semiconductor company headquartered in Dallas, Texas, designing and manufacturing analog and embedded processing chips for industrial, automotive, and consumer markets.

The LMV3xx product line was developed to replace legacy LM358/LM324 in space-constrained, battery-powered, and low-voltage systems - prioritizing rail-to-rail output, ground-sensing inputs, and ultra-low quiescent current without sacrificing AC performance.

FAQ

What is the maximum supply voltage for LMV358IPWRG4?

The absolute maximum supply voltage for LMV358IPWRG4 is 5.5 V. Operation above this voltage risks permanent damage. Recommended operating range is 2.7 V to 5.5 V, with full electrical specifications guaranteed across this span. At 5 V, LMV358IPWRG4 delivers 1 MHz bandwidth and 1 V/μs slew rate while consuming 440 μA total supply current.

Does LMV358IPWRG4 support rail-to-rail input?

No, LMV358IPWRG4 does not support rail-to-rail input. Its input common-mode voltage range extends from –0.2 V (below GND) to VCC–1.7 V at 2.7 V supply, and to VCC–4 V at 5 V supply. However, it does provide true rail-to-rail output swing - within 100 mV of both rails under 10 kΩ load - making it ideal for single-supply systems where output headroom is critical.

Is LMV358IPWRG4 pin-compatible with standard LM358 packages?

No, LMV358IPWRG4 in TSSOP-8 is not pin-compatible with industry-standard LM358 in SOIC-8 or PDIP-8. While both are dual op-amps, LMV358IPWRG4 pinout follows TI's LMV358-specific assignment (1OUT, 1IN–, 1IN+, GND, VCC+, 2OUT, 2IN–, 2IN+), whereas LM358 uses (OUT1, IN–1, IN+1, VCC–, VCC+, OUT2, IN–2, IN+2). Board redesign is required for substitution.

What is the input offset voltage drift over temperature for LMV358IPWRG4?

The average temperature coefficient of input offset voltage (αVIO) for LMV358IPWRG4 is 5 μV/°C. Over the full –40°C to +125°C operating range, this results in a maximum additional offset drift of ±825 μV beyond the room-temperature value. This drift is fully characterized and specified in the datasheet's Electrical Characteristics tables for both 2.7 V and 5 V supply conditions.

Can LMV358IPWRG4 drive capacitive loads directly?

LMV358IPWRG4 can drive capacitive loads up to 100 pF stably without external compensation, as verified in Figure 7 of the datasheet. For loads >100 pF (e.g., LCD panel traces or long cables), a series resistor (20–100 Ω) should be placed between the output and capacitance to maintain phase margin ≥60° and prevent oscillation - confirmed by stability testing across temperature and supply voltage.
