描述 Description

The STPA003 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

STPA003 is extremely robust against several

kinds of fortuitous misconnection.

It is compliant to the most recent OEM

specifications for low voltage operation (the so

called 'start-stop' battery profile during engine

stop).

It includes a DC offset detector and, in

Flexiwatt27 package, a high side driver or a

clipping detector.
