IF filter / amplifier / demodulator for FM

radio receivers

Preliminary specification

TEA6850

FEATURES

• Improved dynamic selectivity and sensitivity because of

tunable IF filter

• Fully integrated, frequency matched FM demodulator

• High linearity

• Unweighted level detector output

• Soft mute

• MPX output for RDS and diversity

• Internal source selector.

GENERAL DESCRIPTION

The TEA6850 is a monolithic bipolar integrated circuit for

IF filtering, FM demodulation and level detection. Using IF

filters tuned by the demodulated signal, dynamic

selectivity and sensitivity are improved.
