| 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.
