Description

PowerSO-36

(slug up)

STPA008ZS is a breakthrough MOSFET

technology class AB audio power amplifier

designed for high power car radio. The fully

complementary 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.

Features

 AEC-Q100 qualified

 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.

STPA008ZS 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 to contribute to environment

protection.

 MOSFET output power stage

 2 Ω driving capability

 Capable to operate down to 6 V (suitable for

start-stop car operation)

 Excellent GSM noise immunity

 Hi-Fi class distortion

 Low output noise
