TDA2050

TDA2050 32 W hi-fi audio power amplifier Features ■ High output power (50 W music power IEC 268.3 rules) ■ High operating supply voltage (50 V) )■ Single or split supply operations t(s■ Very low distortion uc■ Short-circuit protection (OUT to GND) d■ Thermal shutdown ProDescription leteThe TDA 2050 is a monolithic integrated circuit in oa Pentawatt package, intended for use as an saudio class-AB audio amplifier. bThanks to its high power capability the TDA2050 - Ois able to provide up to 35 W true RMS power into )a 4 ohm load at THD = 0%, VS = ±18 V, f = 1 kHz t(sand up to 32 W into an 8 ohm load at THD = 10%, cVS = ±22 V, f = 1 kHz. uMoreover, the TDA2050 delivers typically 50 W dmusic power into a 4 ohm load over 1 sec at roVS = 22.5 V, f = 1 kHz. Obsolete PFigure 1. Test and application circuit Pentawatt V 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.
