Features

 High output power capability:

– 4 x 52 W/4 Ω max.

– 4 x 30 W/4 Ω @ 14.4 V, 1 kHz, 10 %

– 4 x 85 W/2 Ω max.

Description

– 4 x 55 W/2 Ω @ 14.4V, 1 kHz, 10 %

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.

 MOSFET output power stage

 Stop-start and hybrid engines compliant

 Excellent 2  driving capability

 Hi-Fi class distortion

 Low output noise

It is compliant to the most recent OEM

specifications for low voltage operation in start-

stop vehicles, and can sustain hybrid vehicles

battery transitions.

 Standby function and mute function

 Automute at min. supply voltage detection

 Low external component count:

– Internally fixed gain (26 dB)

It includes a DC offset detector and, in

Flexiwatt27 package, a clipping detector.
