The ALM2402-Q1 is a dual high voltage, high current op-amp with protection features that are optimal for driving low impedances and/or high ESR capacitive loads. ALM2402-Q1 operates with single or split power supplies from 5.0 V to 16 V and can output up to 400 mA 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 and henceforth the on-chip power dissipation.

The ALM2402 is packaged in a 12 pin leadless DRR package and 14 pin leaded HTSSOP (preview). Both include a thermally conductive power pad that facilitates heat sinking. The very low thermal impedance of these packages enable optimal current drive with minimal die temperature increase. Providing customers with the ability to drive high currents in harsh temperature conditions. Maximum power dissipation can be determined in the figure below.
