Overview

FM NOISE CANCELLER S1A2272A01 INTRODUCTION The S1A2272A01 is a monolithic integrated circuit for the FM noise canceller used in car stereos.
It is used in combination with a PLL FM multiplex demodulator with a pilot signal canceller.
16−SOP−225A FEATURES • • • • • • Operation voltage range: VCC = 8V − 15V Low quiescent circuit current Low distortion: THD = 0.
02% at VI = 300mV Pilot signal compensation Built-in monostable multivibrator.
Variable input type noise AGC system.
