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.
