TDA2050_11 Datasheet, PDF (1/18 Pages) STMicroelectronics – 32 W hi-fi audio power amplifier

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)
■ Thermal shutdown
Description
The TDA 2050 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%, V_S = ±18 V, f = 1 kHz
and up to 32 W into an 8 ohm load at THD = 10%,
V_S = ±22 V, f = 1 kHz.
Moreover, the TDA2050 delivers typically 50 W
music power into a 4 ohm load over 1 sec at
V_S = 22.5 V, f = 1 kHz.

The high power and very low harmonic and
crossover distortion (THD = 0.05% typ, at
V_S = ±22 V, P_O = 0.1 to 15 W, R_L= 8 ohm,
f = 100 Hz to 15 kHz) make the device most
suitable for both hi-fi and high-end TV sets.
