Description



Stereo per channel
VCC=9V;RL=4?/3W
VCC=9V;RL=8?/2W

Bridge Application
VCC=9V;RL=8?/5W
VCC=9V;RL=4?/8W

Supply Voltage min = DC3v @ 500mA
Supply Voltage max = DC12v @ 500mA
Supply Voltage recommended = DC9v @500mA

DESCRIPTION
Above circuits are based on TEA2025 is a monolithic integrated audio amplifier in a 16-pin plastic dual in line package manufactured by UTC .Circuit has an Internal Thermal Protector. It is designed for portable cassette players and radios. You can also use it as your PC Audio Amplifier. A few external components required to build this circuit.
