UTC1353
LINEAR INTEGRATED CIRCUIT
TV SOUND SYSTEM
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
