TDA2050V STMicroelectronics

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 Very low distortion Short-circuit protection (OUT to GND) Pentawatt V Thermal shutdown The high power and very low harmonic and Description crossover distortion (THD = 0.05% typ, at V = 22 V, P = 0.1 to 15 W, R = 8 ohm, S O L The TDA 2050 is a monolithic integrated circuit in f = 100 Hz to 15 kHz) make the device most a Pentawatt package, intended for use as an suitable for both hi-fi and high-end TV sets. audio class-AB audio amplifier. Thanks to its high power capability the TDA2050 Table 1. Device summary is able to provide up to 35 W true RMS power into a 4 ohm load at THD = 0%, V = 18 V, f = 1 kHz Order code Package S and up to 32 W into an 8 ohm load at THD = 10%, TDA2050V Pentawatt vertical V = 22 V, f = 1 kHz. S Moreover, the TDA2050 delivers typically 50 W music power into a 4 ohm load over 1 sec at V = 22.5 V, f = 1 kHz. S Figure 1.
