TDA2050 is a high-power audio amplifier sold by Dinghao Electronics. It has a rated output power of 50W, a wide operating voltage range, supports single or dual power supply, low distortion, and has short circuit protection and thermal shutdown functions.
The TDA2050 is a monolithic Pentawatt‑package integrated circuit designed for Class‑AB audio amplification. It delivers up to 35 W into a 4 Ω load (music power) and 32 W into an 8 Ω load, with very low total harmonic distortion and short‑circuit protection.
The device can be used in split‑supply or single‑supply configurations, and includes thermal shutdown at 150 °C. Typical applications include Hi‑Fi audio equipment and high‑class TV sets. Detailed electrical characteristics, recommended external component values and layout guidelines are provided in the datasheet.
