TDA8947J
4-channel audio amplifier (SE: 1 W to 25 W; BTL: 4 W to 50 W)
Rev. 01 — 06 February 2004
Preliminary data
1.
General description
The TDA8947J contains four identical audio power amplifiers. The TDA8947J 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 TDA8947J comes in a 17-pin Dil-Bent-Sil (DBS) power package. The TDA8947J
is pin compatible with the TDA8944AJ and TDA8946AJ.
The TDA8947J 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.
