E-TDA7391PDTR
Differential input, single BTL output power amplifier with stand-by and clip detection
September 2013 Doc ID 6326 Rev 5 1/12
TDA7391PD
32 W bridge car radio amplifier
Features High power capability: 40 W/3.2  EIAJ 32 W/3.2  @ VS = 14.4 V, f = 1 kHz,
d = 10 % 26 W/4 @ 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 stand-by
operations
Protections Short circuit (to GND, to VS, across the load) Very inductive loads Chip over temperature Load dump Open GND ESD
Description
The TDA7391PD 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
equipment. 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.
