The TDA2050 is an audio class AB audio amplifier produced by Texas Instruments. The chip uses Pentawatt packaging, has high output power (50W music power IEC 268.3 rules), high operating voltage (50V), single or split power supply operations, very low distortion, short circuit protection (output to GND) and thermal shutdown function.
The TDA2050 is a monolithic audio power amplifier IC in a Pentawatt package, designed for Hi‑Fi and high‑class TV applications. It can deliver up to 35 W RMS into a 4 Ω load and 32 W into an 8 Ω load while maintaining very low total harmonic distortion.
The datasheet provides absolute maximum ratings, detailed electrical characteristics, recommended external component values for split‑ and single‑supply configurations, and mechanical dimensions of the package. It also includes typical performance curves such as output power versus supply voltage and distortion versus frequency.
