TDA4200-3

The TDA4200-3 is a kind of FM IF component with a special demodulator for application in car radios. The sensitivity level of the input amplifier can be adjusted for applications with search tuning mode. Besides, a search tuning stop pulse is generated. The device is intended for application in car radios and home receivers which require a search tuning stop pulse.

There are some features of TDA4200-3 as follows: (1)7-state limiter amplifier; (2)produce demodulator; (3)AFC output; (4)field strength dependent volume control; (5)generaton of search tuning stop pulse; (6)adjustable muting depth.
