This is 250 milliwatts amplifier scheme design with TDA2822. This low power amplifier generates 250 mW on each channel, can be used for general purposed application such as walkman, mp3 player, radio etc. This may well configured to operate in stereo or bridge, which is obtained more power in mono channel. It is also ideal for use as a preamp in high power amplifiers. It can be supplied with 3 to 6 volts and 500 milliamps, without detracting from the quality of sound. It is useful to replace portable radios and amplifiers of gaming gadgets.
