TDA2050 is a power amplifier chip produced by Philips. It has the characteristics of high output power, high operating voltage, single or dual power supply, low distortion, short circuit protection and thermal shutdown. It is suitable for high-fidelity audio and high-end TV sets.
The TDA2050 is a monolithic integrated circuit in a Pentawatt package designed for class‑AB audio amplification. It can deliver up to 32 W into an 8 Ω load and 35 W into a 4 Ω load, with very low distortion and built‑in short‑circuit and thermal protection. The document includes a description of the device, ordering numbers, and typical split‑supply and single‑supply application circuits.
Detailed electrical characteristics are listed, including supply voltage range, quiescent drain current, input bias current, output power, total harmonic distortion, slew rate, gain, bandwidth, input resistance, and thermal shutdown temperature. Mechanical dimensions, pin connections, and a legal disclaimer conclude the datasheet.
