Dual Channel Audio Power Amplifier-1521

May 29, 2025

CD1521 is a 2 * 12W low distortion dual channel audio power amplifier. It is characterized by high output power, low distortion, low output offset voltage, good channel balance, and overheating and short circuit protection. When the power is turned on and off, it has the function of suppressing noise. The device is particularly suitable for stereo feeds (such as stereo radios and stereo TV stereos). It has few peripheral components and is especially suitable for beginners. I also used it to make a small power amplifier, but now I add a tone to the back and still use it!

CD1521 adopts 9-lead plastic single in-line package. For structural block diagram (replacement model) see: TDA1521.

Typical circuit:

2. Single power supply operation.
