3 Description
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.
