Product Details

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.

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
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
