Description

The STPA002 is a MOSFET class AB audio

power amplifier, designed for high-power car

radio. In addition to the outstanding output current

capability and distortion performance, the

STPA002 is extremely robust against several

kinds of fortuitous misconnections.

It is compliant to the most recent OEM

specifications for low voltage operation in start-

stop vehicles, and can sustain hybrid vehicles

battery transitions.

It includes a DC offset detector and, in

Flexiwatt27 package, a clipping detector.
