DESCRIPTION
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.
   
■ HIGH POWER CAPABILITY:
    40W/4Ω MAX
    35W/4Ω EIAJ
    45W/3.2Ω MAX
    40W/3.2Ω EIAJ
    32W/3.2Ω @ VS = 14.4V, f = 1KHz, d = 10%
    26W/4Ω @ VS = 14.4V, f = 1KHz, 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 (30dB)
    - NO SVR CAPACITOR
■ ST.-BY FUNCTION (CMOS COMPATIBLE)
■ PROGRAMMABLE TURN-ON/OFF DELAY
■ NO AUDIBLE POP DURING MUTE AND STBY OPERATIONS
   
PROTECTIONS:
■ SHORT CIRCUIT (TO GND, TO VS, ACROSS
    THE LOAD)
