Is there a pin-compatible replacement for LMV358?

Yes, many dual op-amps like the LM358 and LM2904 share the same standard SOP-8 pinout. However, pin compatibility does not guarantee electrical compatibility; key parameters like voltage, power, and output swing must be verified.

What risks should I check before replacing LMV358?

Key risks include: 1) Minimum supply voltage (many alternatives need >3V). 2) Power consumption (LMV358 is very low power). 3) Output swing (LMV358 is rail-to-rail, many are not). 4) Input bias current for high-impedance circuits.

LMV358 Alternatives, Datasheet & Cross Reference | IDCHIP

The LMV358 is a low-voltage, low-power dual operational amplifier with rail-to-rail I/O, ideal for battery-powered devices. Finding a direct replacement requires matching these key features.

Mismatch in voltage, power, and output swing.

Package risklow

SOP-8 is a standard package with compatible pinouts.

Can it be replaced directly?

No direct, drop-in replacement has been identified. Common alternatives like the LM358 have significant parametric differences and are high-risk.

Best replacement path

Search for dual op-amps with rail-to-rail output, supply voltage down to ~2V, and quiescent current under 100µA per channel.

Main risk

The primary risks are higher minimum operating voltage, much higher power consumption, and lack of rail-to-rail output swing.

Recommended alternatives

A functional alternative in the same package, but with higher power use, higher minimum voltage, and non-rail-to-rail output.

Questions & answers

The best alternative will be another low-voltage (2.1V-5.5V), low-power, rail-to-rail dual op-amp in an SOP-8 package. Standard op-amps like the LM358 are not ideal due to higher voltage and power requirements.
