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.

Key features
