Description

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.

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.
