Quad bridge power amplifiers designed for high-power vehicle radios

STMicroelectronics' STPA003 quad bridge power amplifiers are MOSFET class AB audio power devices designed for high-power car radio applications. In addition to outstanding output current capability and distortion performance, the STPA003 is extremely robust against misconnection. They are compliant with the most recent OEM specifications for low-voltage operation (such as 'start-stop' battery profile during engine stop). They include a DC offset detector and a high side driver or a clipping detector.
