TFA9842J  
2-channel audio amplifier; SE: 1 W to 7.5 W; BTL: 2 W to 15 W  
Rev. 01 — 26 April 2004  
Preliminary data  
1. General description  
The TFA9842J contains two identical audio power amplifiers. The TFA9842J can be  
used as two Single-Ended (SE) channels with a fixed gain of 26 dB or one  
Bridge-Tied Load (BTL) channel with a fixed gain of 32 dB.  
The TFA9842J comes in a 9-pin DIL-bent-SIL (DBS9P) power package. The  
TFA9842J is pin compatible with the TFA9841J and TFA9843J.  
The TFA9842J 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 7.5 W; BTL: 2 W to 15 W operation possibility  
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 the TFA9841J and TFA9843J.  
3. Applications  
Television  
PC speakers  
Boom box  
Mini and micro audio receivers.
