ST TDA2050 handbook
TDA2050 is a monolithic integrated circuit in a 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 35 W true RMS power into a 4 ohm load at THD = 0%, VS = ±18 V, f = 1 kHz and up to 32 W into an 8 ohm load at THD = 10%, VS = ±22 V, f = 1 kHz. Moreover, the TDA2050 delivers typically 50 W music power into a 4 ohm load over 1 sec at VS = 22.5 V, f = 1 kHz. The high power and very low harmonic and crossover distortion (THD = 0.05% typ, at VS = ±22 V, PO = 0.1 to 15 W, RL= 8 ohm, f = 100 Hz to 15 kHz) make the device most suitable for both hi-fi and high-end TV sets.
