The TDA7265 is an integrated circuit (IC) designed for use as an audio amplifier and is a member of the STMicroelectronics TDA series of audio amplifiers.
It is specifically a dual bridge amplifier, which means it can be used to amplify audio signals in stereo (two-channel) applications and is a class AB Stereo Audio Power Amplifier IC that produces an output of 25W + 25W on each channel and comes in a Multiwatt-11 Package.
It is a high-performance dual audio power amplifier IC designed for Hi-Fi stereo systems, home theater setups, and DIY amplifier projects. Manufactured by STMicroelectronics, this Class AB amplifier delivers 25W per channel into an 8-ohm load with exceptional sound quality, low distortion, and built-in protection features—all packed in a compact Multiwatt-11 package.
Whether you’re building a new stereo amplifier or replacing a faulty chip in a TV or subwoofer system, the TDA7265 offers a reliable and robust solution with minimal external components required.
