DESCRIPTION
The UTC1353 is a monolithic integrated circuit designed for the SIF and audio section in television receivers. This IC has all functions including sound IF amplifier, FM detector, DC volume control circuit, audio output amplifier with 2.4Watts output power and voltage regulator.

FEATURES
*Wide operating voltage (9V to 18V)
2.4W, at Vcc=18V, RL=8Ω(For 17” TV)
1.2W, at Vcc=12V, RL=8Ω(For 12” TV)
*linear volume control
*Low Harmonic distortion
*Differential peak detector
*Enough attenuation (typical, 80dB) by squelch circuit
