DESCRIPTION
The TDA 2050 is a monolithic integrated circuit, intended for use as an audio class AB audio amplifier. Thanks to its high power capability 
TDA2050 is able to provide up to 35W true rms power into 4 ohm load @ THD =10%, VS = ±18V, f = 1KHz and up to 32W into 8ohm load @THD = 10%, VS = ±22V, f = 1KHz. Moreover.
TDA 2050 delivers typically 50W music power into 4 ohm load over 1 sec at VS=22.5V, f = 1KHz. The high power and very low harmonic and crossover distortion THD = 0.05% typ, @ VS = ±22V, PO = 0.1 to 15W, RL=8ohm, f = 100Hz to 15KHz) make the device most suitable for both HiFi and high class TV sets.
