Optimus TDA2050 32Wx2 Stereo Amplifier
Price in Sri Lanka

The TDA2050 32W × 2 Stereo Amplifier Module is a high-performance audio solution designed to deliver clear and powerful stereo sound for a wide range of applications. Built using two TDA2050 Class AB power amplifier ICs, the module provides dedicated left and right channel amplification with low distortion and excellent audio fidelity. It is capable of amplifying low-level audio signals from sources such as mobile phones, Bluetooth receivers or MP3 players and directly driving passive loudspeakers.

The module features an onboard bridge rectifier and large filter capacitors, allowing it to be powered directly from an AC source while generating stable dual DC supply rails for reliable operation. With proper heat sinking and supply conditions, it delivers up to 32W per channel, making it suitable for both educational use and high-quality audio system designs.
