Produk asli dari UTC Unisonic Technologies Mfr.Part #: TDA2050L-TB5-T
UTC adalah perusahaan lokal dari China. STMicroelectronics sudah discontinue produk ini. Tidak bisa di beli lagi dari distributor resmi sekalipun. Produk dengan marking ST hampir pasti KW. Produk dari UTC lebih sering dibicarakan di forum2 DIY. Mungkin alternatif terbaik.
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
