TFA9843J Datasheet | NXP Semiconductors

2-channel audio amplifier (SE: 1 W to 20 W or BTL: 4 W to 40 W) Rev. 02 - 19 January 2004 Preliminary data 1. General description The TFA9843J contains two identical audio power amplifiers. The TFA9843J can be used as two Single-Ended (SE) channels with a fixed gain of 26 dB or one Bridge-Tied Load (BTL) channel with a fixed gain of 32 dB. The TFA9843J es in a 9-pin DIL-bent-SIL (DBS7P) power package. The TFA9843J is pin patible with the TFA9842J and TFA9841J. The TFA9843J 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...
