TDA8947J

The TDA8947Jcontains 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

This is the 2.1 circuit diagram using TDA8947J. This amplifier circuit has 3 audio inputs and 3 audio outputs. One can make 50 watts, and the other 2 are 25+25
