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.

Hardware development


This board is designed for customer evaluation of the ALM2402-Q1 device, specifically the ALM2402QDRRRQ1 orderable part number. The EVM is set up as a basic unity gain amplifier. There are many slots on the board where resistors are not populated; these allow the customer to add filters, custom (...)

  • Test points for all power, input, and output
  • Footprints which allow the customer to populate their own components
  • Large footprints to allow for testing of heavy output loads
  • Zener diode configuration to allow bidirectional overtemperature flag (OTF) operation
