TDA2822 is an ideal Op amp for low output applications. 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.
