Description
The TDA7391PD is a bridge class AB audio power amplifier specially intended for car radio high power applications.
   
Features
■ High power capability:
    – 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
■ Stand-by function (CMOS compatible)
■ Programmable turn-on/off delay
■ No audible pop during mute and stand-by
    operations
   
Protections
■ Short circuit (to GND, to VS, across the load)
■ Very inductive loads
■ Chip over temperature
■ Load dump
■ Open GND
■ ESD
