Manufacturer Part Number
UTC1353
Description
Manufacturer
Hangzhou Silan Microelectronics
Datasheet
UTC1353
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.
*Wide operating voltage (9V to 18V)
*linear volume control
*Low Harmonic distortion
*Differential peak detector
*Enough attenuation (typical, 80dB) by squelch circuit
The UTC1353 is a monolithic integrated circuit
2.4W, at Vcc=18V, R
1.2W, at Vcc=12V, R
