Description

 MOSFET output power stage

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.

 Capable to operate in low voltage conditions

(e.g.: “Start - Stop”)

 Excellent GSM noise immunity

 Excellent 2 Ω driving capability

 Hi-Fi class distortion

It is compliant to the most recent OEM

specifications for low voltage operation (the so

called 'start-stop' battery profile during engine

stop).

 Low output noise

 Standby function and mute function

 Automute at min. supply voltage detection

 Low external component count:

It includes a DC offset detector and, in

Flexiwatt27 package, a high side driver or a

clipping detector.

– Internally fixed gain (26 dB)
