32 Watt Audio Amplifier W/
25+/- Dc Power Supply

2. Synopsis
 The amplifier is built around a single integrated circuit (IC), the
TDA2050V which is produced by STMicroelectronics. From the
data sheet, the TDA2050V is intended for use as a Class-AB hi-fi
audio amplifier. The chip will operate within a supply voltage
range of +/-4.5V to +/-25V. At about 25W of power output the
efficiency is about 65%. One thing to note is that the gain of the
circuit needs to be at least 24dB to maintain stability.
 The amplifier was built to drive a pair Hi-Fi Speaker. The speakers
are 4 ohms .The amplifier can be driven by most line-level sources
such as an mp3 player, cd player, tuner and so on. The small
TDA2050V chip can sound very well
