STPA008 is a breakthrough MOSFET technology

class AB audio power amplifier designed for high

power car radio. The fully complementary

Features

P-Channel/N-Channel output structure allows a

rail to rail output voltage swing which, combined

with high output current and minimized saturation

losses sets new power references in the car-radio

field, with unparalleled distortion performances.

 High output power capability:

– 4 x 50 W/4 Ω Max.

– 4 x 28 W/4 Ω @ 14.4 V, 1 kHz, 10 %

– 4 x 72 W/2 Ω Max.

 MOSFET output power stage

 2 Ω driving capability

STPA008 can operate down to 6V and this makes

the IC compliant to the most recent OEM

specifications for low voltage operation (so called

'start-stop' battery profile during engine stop),

helping car manufacturers to reduce the overall

emissions and thus contributing to environment

protection.

 Capable to operate down to 6 V (suitable for

start-stop car operation)

 Excellent GSM noise immunity

 Hi-Fi class distortion

 Low output noise
