LMX321

Low-power, general-purpose operational amplifier
  • active Active

The LMX3xx series is a set of single, dual, and quad low-voltage, general-purpose, operational amplifiers. These devices can operate from 2.3 V to 5.5 V with a typical current consumption of 120 μA per channel. The LMX3xx series offers a rail-to-rail output and an input common-mode voltage that includes ground.

The LMX3xx series also exhibits a 1.3 MHz gain bandwidth and they can drive capacitive loads. The devices are stable while operating at unity gain. They are offered with industry standard pinouts in tiny packages.
