standard

Description

STPA008 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.

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.
