General description
The TDA8948J contains four identical audio power amplifiers. The TDA8948J can
be used as four Single-Ended (SE) channels with a fixed gain of 26 dB, two
times Bridge-Tied Load (BTL) channels with a fixed gain of 32 dB or two times
SE channels (26 dB gain) plus one BTL channel (32 dB gain) operating as a 2.1
system.
The TDA8948J comes in a 17-pin Dil-Bent-Sil (DBS) power package. The TDA8948J
is pin compatible with the TDA8944AJ, TDA8946AJ and TDA8947J.
The TDA8948J 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 heat
sink and ambient temperature) allow it.
