  • The STPA002 is a MOSFET class AB audio power amplifier, designed for high-power car radio. In addition to the outstanding output current capability and distortion performance, the STPA002 is extremely robust against several kinds of fortuitous misconnections.

    It is compliant to the most recent OEM specifications for low voltage operation in start-stop vehicles, and can sustain hybrid vehicles battery transitions.
    It includes a DC offset detector and, in Flexiwatt27 package, a clipping detector.

    Key Features

    • High output power capability:
      • 4 x 52 W/4 Ω max.
      • 4 x 30 W/4 Ω @ 14.4 V, 1 kHz, 10 %
      • 4 x 85 W/2 Ω max.
      • 4 x 55 W/2 Ω @ 14.4V, 1 kHz, 10 %
    • MOSFET output power stage
    • Stop-start and hybrid engines compliant
    • Excellent 2 Ω driving capability
    • Hi-Fi class distortion
    • Low output noise
    • Standby function and mute function
    • Automute at min. supply voltage detection
    • Low external component count:
      • Internally fixed gain (26 dB)
      • No external compensation
      • No bootstrap capacitors
    • Protections:
      • Output short circuit to GND, to Vs, across the load
      • Very inductive loads
      • Overrating chip temperature with soft thermal limiter
      • Output DC offset detection
      • Load dump voltage
      • Fortuitous open GND
      • Reverse battery
      • ESD
