www.DataSheet4U.com 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.
