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.
