  • The TDA7391 is a bridge class AB audio power amplifier specially intended for car radio high power applications.

    The high power capability together with the possibility to operate either in differential input mode or single ended input mode makes it suitable for boosters and high end car radio equipments. The exclusive fully complementary output stage and the internal fixed gain configuration drop the external component count.
    The on board clipping detector allows easy implementation of gain compression systems.

    主要特性

    • High power capability:
      • 40 W/4 Ω max
      • 35 W/4 Ω EIAJ
      • 45 W/3.2 Ω max
      • 40 W/3.2 Ω EIAJ
      • 32 W/3.2 Ω @ VS= 14.4 V, f = 1 kHz, d = 10 %
      • 26 W/4 Ω @ VS= 14.4 V, f = 1 kHz, d = 10 %
    • DIfferential inputs (either single ended or differential input signal are accepted)
    • Minimum external component count:
      • No bootstrap capacitors
      • No Boucherot cells
      • Internally fixed gain (30 dB)
      • No SVR Capacitor
    • Standby function (CMOS compatible)
    • Programmable turn-on/off delay
    • No audible pop during mute and standby operations
    • Protections:
      • Short circuit (to GND, to VS, across the load)
      • Very inductive loads
      • Chip over temperature
      • Load dump
      • Open GND
      • ESD
