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. The STPA001 can operate down to 6 V and this makes the IC compliant to the most recent OEM specifications for low voltage operation (so called 'start-stop' batte...
