TFA9842BJ  
2-channel audio amplifier (SE: 1 W to 7.5 W)  
Rev. 01 — 1 March 2004  
Preliminary data sheet  
1. General description  
The TFA9842BJ contains two identical audio power amplifiers. The TFA9842BJ can be  
used as two Single-Ended (SE) channels with a fixed gain of 26 dB.  
The TFA9842BJ comes in a 9-pin DIL-bent-SIL (DBS9P) power package. The TFA9842BJ  
is pin compatible with the TFA9841J, TFA9842J, TFA9843J and the TFA9843BJ.  
The TFA9842BJ 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  
1 W to 7.5 W operation possibility  
Soft clipping  
Standby and mute mode  
No on or 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, TFA9842J, TFA9843J and the TFA9843BJ.  
3. Applications  
Televisions  
Monitors  
PC speakers  
Boom boxes  
Mini and micro audio receivers.
