TFA9842AJ  
7.5 W stereo power amplifier with volume control  
Rev. 01 — 28 April 2006  
Preliminary specification  
1. General description  
The TFA9842AJ contains two identical audio power amplifiers. The TFA9842AJ can be  
used as two Single-Ended (SE) channels with a volume control. The maximum gain is  
26 dB.  
The TFA9842AJ comes in a 9-pin DIL-bent-SIL (DBS9P) power package. The TFA9842AJ  
is pin compatible with the TFA9843AJ, TFA9843(B)J, TFA9842(B)J and TFA9841J. The  
difference between the TFA9843AJ and the TFA9843(B)J, TFA9842(B)J, TFA9841J is the  
functionality of pin 7. The TFA9843AJ has a Volume Control (VC) on pin 7. The  
TFA9843(B)J, TFA9842(B)J and TFA9841J have a mode select (MODE) on pin 7.  
The TFA9842AJ 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  
I 2 channel SE: 1 W to 7.5 W operation possibility  
I Soft clipping  
I Input clamps  
I Volume control  
I Standby and Mute mode  
I No on or off switching plops  
I Low standby current  
I High supply voltage ripple rejection  
I Outputs short-circuit protected to ground, supply and across the load  
I Thermally protected  
I Pin compatible with the TFA9843AJ, TFA9843(B)J, TFA9842(B)J and TFA9841J  
3. Applications  
I CRT TV and LCD TV  
I Monitors  
I PC speakers  
I Boom box  
I Mini and micro audio receivers
