Description
This is 25 +25W STEREO AMPLIFIER WITH MUTE & ST-BY. A stereo amplifier, often simply referred to as an “amp,” is an electronic device designed to amplify audio signals in a stereo audio system. Stereo amplifiers are a fundamental component of audio systems, providing the necessary power to drive speakers and reproduce sound with clarity and fidelity.
The TDA7265 is class AB dual Audio power amplifier assembled in the Multiwatt package, specially designed for high quality sound application as Hi-Fi music centers and stereo TV sets.
A Class AB dual audio power amplifier is an electronic amplifier that is designed to amplify audio signals with two channels (typically left and right) using Class AB amplifier topology. Class AB amplifiers are known for their efficiency and good linearity, making them suitable for high-quality audio reproduction.
