TFA9841J
1-channel audio ampli鏗乪r (SE: 1 W to 7.5 W)
Rev. 01 鈥?06 February 2004
Preliminary data
1. General description
The TFA9841J contains one audio power ampli鏗乪r. The TFA9841J can be used as
one Single-Ended (SE) channel with a 鏗亁ed gain of 26 dB.
The TFA9841J comes in a 9-pin DIL-bent-SIL (DBS9P) power package. The
TFA9841J is pin compatible with the TFA9842J and TFA9843J.
The TFA9841J 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 (external heatsink and ambient temperature) allow it.
