  • The TDA7388A is a new technology class AB audio power amplifier in Flexiwatt27 package designed for high end car radio applications.

    Thanks to the fully complementary PNP/NPN output configuration the TDA7388A allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced components count allows very compact sets.
    The TDA7388A is also equipped with Clipping detector and Offset detector features.

    Key Features

    • High output power capability:
      • 4 x 42 W / 4 Ω max.
      • 4 x 27 W / 4 Ω @ 14.4 V, 1 kHz, 10 %
    • Low distortion
    • Low output noise
    • Standby function
    • Mute function
    • Automute at min. supply voltage detection
    • Low external component count:
      • Internally fixed gain (26 dB)
      • No external compensation
      • No bootstrap capacitors
    • Clipping detector
    • Offset detector
    • Diagnostic facility for:
      • Out to GND short
      • Out to VSshort
      • Thermal shutdown
    • Protections:
      • Output short circuit to GND, to VS, across the load
      • Very inductive loads
      • Overrating chip temperature with soft thermal limiter
      • Load dump voltage
      • Fortuitous open GND
      • Output DC offset detector
      • Reversed battery
      • ESD
