TFA9843BJ 2-channel audio amplifier (SE: 1 W to 20 W) Rev. 01 — 4 May 2004 Preliminary data sheet 1. General description The TFA9843BJ contains two identical audio power amplifiers. The TFA9843BJ can be used as two Single-Ended (SE) channels with a fixed gain of 26 dB. The TFA9843BJ comes in a 9-pin DIL-bent-SIL (DBS9P) power package. The TFA9843BJ is pin compatible with the TFA9841J, TFA9842J, TFA9842BJ and the TFA9843J. The TFA9843BJ 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.
