TDA2030A – 18W Hi-Fi Amplifier, 35W Driver

The TDA2030A is a high-quality audio amplifier chip in mono or stereo configuration originally developed by SGS-THOMSON. The chip is a silicon chip housed in a 14-pin dipping package and is capable of up to 18W of maximum power.

The UTC TDA2030A is a monolithic IC intended for use as low frequency class AB amplifier. With Vs=max=44V it is particularly suited for more reliable applications without regulated supply and for 35W driver circuits using low-cost complementary pairs.
