The fully complementary P-Channel/N-Channel output structure allows a High output power capability: rail to rail output voltage swing which, combined 4 x 50 W/4 Max. with high output current and minimized saturation 4 x 28 W/4 14.4 V, 1 kHz, 10 % losses sets new power references in the car-radio 4 x 72 W/2 Max. field, with unparalleled distortion performances. MOSFET output power stage STPA008 can operate down to 6V and this makes 2 driving capability the IC compliant to the most recent OEM specifications for low voltage operation (so called Capable to operate down to 6 V (suitable for start-stop battery profile during engine stop), start-stop car operation) helping car manufacturers to reduce the overall Excellent GSM noise immunity emissions and thus contributing to environment Hi-Fi class distortion protection.
