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
