TDA2050 32W Hi-Fi AUDIO POWER AMPLIFIER HIGH OUTPUT POWER (50W MUSIC POWER IEC 268.3 RULES) HIGH OPERATING SUPPLY VOLTAGE (50V) SINGLE OR SPLIT SUPPLY OPERATIONS VERY LOW DISTORTION SHORT CIRCUIT PROTECTION (OUT TO GND) THERMAL SHUTDOWN DESCRIPTION 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. TEST AND APPLICATION CIRCUIT Pentawatt ORDERING NUMBERS: TDA2050V TDA2050H 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.
