The TDA2050 is a high power audio amplifier chip from Unisonic Technologies Co., LTD. Its features include high output power, high operating voltage, single or split supply operations, low distortion, short circuit protection, etc.
The TDA2050 is a monolithic linear integrated circuit designed as a class‑AB audio power amplifier capable of delivering about 50 W into a 4 Ω load at 1 kHz with a 22.5 V supply. It features high output power, wide supply voltage range, low distortion, short‑circuit protection, and thermal shutdown, making it suitable for Hi‑Fi and high‑class TV applications.
The datasheet lists absolute maximum ratings, electrical characteristics, and typical application circuits for both split‑supply and single‑supply configurations. Graphs illustrate output power versus supply voltage, total harmonic distortion, efficiency, and quiescent current across operating conditions.
