ESD 4 x 30 W/4 14.4 V, 1 kHz, 10 % 4 x 85 W/2 max. Description 4 x 55 W/2 14.4V, 1 kHz, 10 % The STPA002 is a MOSFET class AB audio MOSFET output power stage power amplifier, designed for high-power car Stop-start and hybrid engines compliant radio. In addition to the outstanding output current capability and distortion performance, the Excellent 2 driving capability STPA002 is extremely robust against several Hi-Fi class distortion kinds of fortuitous misconnections. Low output noise It is compliant to the most recent OEM Standby function and mute function specifications for low voltage operation in start- Automute at min. supply voltage detection stop vehicles, and can sustain hybrid vehicles battery transitions. Low external component count: Internally fixed gain (26 dB) It includes a DC offset detector and, in Flexiwatt27 package, a clipping detector. Table 1.
