The TDA 2050 is a monolithic integrated circuit in Pentawatt package, intended for use as an audio class AB audio amplifier. Thanks to its high power capability the 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, the 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.

Maybe anyone want assemble a mini amps for rooms audio? IC-Amp TDA2050 maybe this one can be a choice. besides the price is very affordable as well sound produced can spoil our ears. said the IC-Amp TDA2050 one is a rival LM1875 (though still better LM1875). This circuit scheme and pcb layout :
TDA2050 Power Amplifier Circuit High output power, low distortion, HiFi power amplifier for your home audio system. Maximum output at 4 ohm speaker is 35 watts, while the 8 ohm speaker is only 15 watts. This circuit must use a good power supply so that the sound quality could be as expected.
