Sales Briefcase
  • The TDA7381 is a class AB audio power amplifier in Flexiwatt25 package designed for car radio applications. Thanks to the fully complementary PNP/NPN output configuration the TDA7381 allows a rail to rail output voltage swing with no need of bootstrap capacitors..

    The extremely reduced components count allows very compact sets. The on-board clipping detector simplifies gain compression operations. The fault diagnostics makes it possible to detect mistakes during car-radio assembly and wiring in the car.

    主要特性

    • High output power capability:
      • 4 x 30 W/4 Ω max.
      • 4 x 25 W/4 Ω EIAJ
      • 4 x 18 W/4 Ω @ 14.4 V, 1 kHz, 10 %
      • 4 x 15 W/4 Ω @ 13.2 V, 1 kHz, 10 %
    • Clipping detector
    • Low distortion
    • Low output noise
    • Standby function
    • Mute function
    • Automute at min. supply voltage detection
    • Diagnostics facility for:
      • Clipping
      • Out to GND short
      • Out to VSshort
      • Thermal shutdown
    • 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
      • Load dump voltage
      • Fortuitous open GND
      • Reversed battery
      • ESD protection
