TDA2050
LINEAR INTEGRATED CIRCUIT
32W HI-FI AUDIO POWER
AMPLIFIER
DESCRIPTION
The UTC TDA2050 is a monolithic integrated circuit with high
power capability and is designed to use as an class AB audio
amplifier. It can deliver typically 50W music power into 4Ω load
over 1 sec at VS=22.5V, f = 1KHz.
The device is most suitable for both Hi-Fi and high class TV sets
on the strength of its high supply voltage and very low harmonic and
crossover distortion.
FEATURES
* 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

NOTE: If the supply voltage is lower than 40V and the load is 8Ω(or more), a lower value of C2(i.e. 22µF) can be
used. C7 can be larger than 1000µF only if the supply voltage does not exceed 40V.
