TDA 7053 Stereo Audio Amplifier Circuit


Posted on Feb 5, 2014

This is a 1 watt stereo audio amplifier circuit using IC TDA 7053 from Philips. It is particularly suited to battery operation, providing 1 watt per channel from only a 6V DC supply. It will operate best from 6 12 V DC and requires no heat-sink for normal use. The TDA7053 Integrated Circuit does nearly all the work, so there are only a few ext

ernal components. C1 and C2 provide power supply decoupling or filtering. R1 and R2 provide a DC ground reference for the input signals, and may be increased if your source requires a higher load impedance. Do not use more than 100k ohms. Since the amplifier circuit in BTL configuration, the outputs are floating with respect to ground. Therefore NO output leads should be connected to ground. The Philips data sheet contains all the necessary information about the TDA7053.
