Product details

Single-supply rail-to-rail op-amp for 0.9 V to 3 V rails

Its key differentiator is the supply range spanning 0.9 V to 3 V, which allows direct operation from a single alkaline or NiMH cell without a boost converter. The quiescent supply current is 570 µA, making it suitable for always-on sense circuits where every microamp counts.

Temperature range and output drive

The output can source or sink 85 mA per channel, which is unusually muscular for a micropower rail-to-rail amplifier — enough to drive the input of an ADC directly or to switch a small relay through a series resistor.

Frequently asked questions

What are the alternatives to LMV951MK/NOPB?

A higher-speed alternative is the TLV9351IDCKR (3.5 MHz GBW, 20 V/µs slew rate, 4.5 V minimum supply), but it requires a higher rail voltage and draws 600 µA supply current. For a multi-channel option, the OPA4374AIPWT offers four CMOS rail-to-rail amplifiers at 6.5 MHz GBW with a 2.7 V minimum supply. Neither is a pin-compatible drop-in; the choice depends on supply voltage headroom and channel count.
