TDA8947J  
4-channel audio amplifier (SE: 1 W to 25 W; BTL: 4 W to 50 W)  
Rev. 01 — 06 February 2004  
Preliminary data  
1. General description  
The TDA8947J contains four identical audio power amplifiers. The TDA8947J can be  
used as: four Single-Ended (SE) channels with a fixed gain of 26 dB, two times  
Bridge-Tied Load (BTL) channels with a fixed gain of 32 dB or two times SE channels  
(26 dB gain) plus one BTL channel (32 dB gain) operating as a 2.1 system.  
The TDA8947J comes in a 17-pin Dil-Bent-Sil (DBS) power package. The TDA8947J  
is pin compatible with the TDA8944AJ and TDA8946AJ.  
The TDA8947J contains a unique protection circuit that is solely based on multiple  
temperature measurements inside the chip. This gives maximum output power for all  
supply voltages and load conditions with no unnecessary audio holes. Almost any  
supply voltage and load impedance combination can be made as long as thermal  
boundary conditions (number of channels used, external heatsink and ambient  
temperature) allow it.  
2. Features  
SE: 1 W to 25 W, BTL: 4 W to 50 W operation possibility (2.1 system)  
Soft clipping  
Standby and mute mode  
No on/off switching plops  
Low standby current  
High supply voltage ripple rejection  
Outputs short-circuit protected to ground, supply and across the load  
Thermally protected  
Pin compatible with TDA8944AJ and TDA8946AJ.  
3. Applications  
Television  
PC speakers  
Boom box  
Mini and micro audio receivers.
