General description
The TFA9842AJ contains two identical audio power amplifiers. The TFA9842AJ can
be used as two Single-Ended (SE) channels with a volume control. The maximum
gain is 26 dB.
The TFA9842AJ comes in a 9-pin DIL-bent-SIL (DBS9P) power package. The
TFA9842AJ is pin compatible with the TFA9843AJ, TFA9843(B)J, TFA9842(B)J and
TFA9841J. The difference between the TFA9843AJ and the TFA9843(B)J,
TFA9842(B)J, TFA9841J is the functionality of pin 7. The TFA9843AJ has a
Volume Control (VC) on pin 7. The TFA9843(B)J, TFA9842(B)J and TFA9841J have a
mode select (MODE) on pin 7.
The TFA9842AJ 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.
