  • 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.

    Key Features

    • Low power consumption: 120 μA at 2.7 V
    • Low supply voltage: 2.3 V - 5.5 V
    • Rail-to-rail output swing
    • Gain bandwidth product: 1.3 MHz
    • Extended temperature range: -40 °C to 125 °C
