Texas Instruments ALM2402-Q1 Dual Operational Amplifier
Texas Instruments ALM2402-Q1 Dual Operational Amplifier is a dual high-voltage, high-current op-amp. It includes protection features that are optimal for driving low impedances and/or high ESR capacitive loads. The ALM2402-Q1 from Texas Instruments operates with single or split power supplies from 5.0V to 16V and can output up to 400mA DC. Each op-amp includes over-temperature flag/shut-down. It also includes separate supply pins for each output stage that allow the user to apply a lower voltage on the output to limit the Voh. This reduces the on-chip power dissipation.
