... The TFA9842J comes in a 9-pin DIL-bent-SIL (DBS9P) power package. The TFA9842J is pin compatible with the TFA9841J and TFA9843J. The TFA9842J 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 ...
