TDA1514A Audio Amplifier 50W

TDA1514A general description:


Here the very simple but powerful amplifier kit which built based on TDA1514A amplifier chip. The circuit is for single channel only, you should build two similar circuit for stereo application. A heatsink is a must to be attached on the IC TDA1514A. This circuit can be used as well as stereoamplifiers Bass in a 5.1 system. TDA1514A Audio Amplifier 50W
