TFA9843BJ
1. General description
2. Features
3. Applications
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. Almost any supply
voltage and load impedance combination can be made as long as thermal boundary
conditions (number of channels used, external heatsink and ambient temperature)
allow it.
