Product details

This combination suits battery-powered sensor interfaces, portable instrumentation, and general-purpose signal conditioning where low power and moderate speed are the priorities.

It will drive a 1 kHz sine wave cleanly at full output swing, but expect significant slew-rate limiting above 100 kHz for large-signal steps. For a 3.3 V ADC driver sampling at 10 kSPS, the settling time is adequate; for a 1 MSPS SAR converter, look to a faster amplifier. Input offset voltage is rated at 250 µV maximum. That is typical for a CMOS op-amp at this price point. For a precision weigh-scale or thermocouple front end requiring sub-100 µV offset, you would need an auto-zero or chopper-stabilized part. For general-purpose buffering, filtering, or level shifting, this is fine. Quiescent current of 107 µA per channel keeps the total supply draw under 250 µA for the dual package. In a battery-powered IoT sensor node running off a CR2032, that is a meaningful saving compared to a 500 µA-per-channel general-purpose op-amp.

No AEC-Q qualification is listed in the record, so it is not explicitly rated for automotive stress grades.

No official second-source alternate is listed, but the OPA4374AIPWT (quad, 5.5 MHz) and TLV9362IDDFR (dual, 10.6 MHz) are faster siblings in the same supply-voltage and temperature envelope if the speed requirement is higher.

Frequently asked questions

When sourcing LMV342IDR, what's the closest functional second-source?

No official second-source alternate is listed. For a faster dual op-amp with similar supply range, consider the TLV9362IDDFR (10.6 MHz, 25 V/µs). The OPA4374AIPWT is a quad option at 5.5 MHz.
