TEA6850 - DSP-based radio tuner one-chip

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.

MAX.

UNIT V mA dB 0.5 220 +85 dB % mV °C ORDERING

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. QUICK.
