TDA4566

The TDA7052 is a classic, low-power, single-channel (mono) audio amplifier IC designed by Philips (now NXP) for battery-operated portable devices like radios and tape players, known for its simplicity, minimal external parts, Bridge-Tied Load (BTL) output for more power, DC volume control (TDA7052A), and built-in protection, delivering about 1W into an 8Ω speaker from a low voltage. It's favored for its efficiency, stability, and ease of use, requiring just a few capacitors for a functional circuit.
