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.
You should build it, listen to it, as a preamplifier or a head phone amplifier. Make changes and listen for the differences. This is how a lot of us got started, experimenting.
Thank you for you reply.I would like to ask that:
Can I use this amp. in my car? If not? What is suitable?
if all you want is 250mW. Most cars need more power as they tend to be noisy environments. In the US, operation of headphones in a car is illegal.
