Preamplifier about audio

Posted by lingl955@yahoo.com on June 27, 2017 at 00:51:52:

I am trying to make an audio amplifier TDA2822 which is a low power stereo Op Amplifier used in Walkman players and Hearing aids.It can give 250 mW output. TDA2822 is an ideal Op amp for low output applications according to the datasheet of TDA2822. It is a good choice as a preamplifier in stereo high power amplifier circuits. It has two inputs and two outputs which can deliver 250 milli watts output power. The amplifier circuit with in the IC is well set for noise free operation. Outputs can be directly coupled to the speakers through the decoupling capacitors.
