GENERAL DESCRIPTION

The TDA3826 is a single FM demodulator system with mute and 6 dB AF amplifier.

Features

• Supply voltage range from 4.5 V to 13.2 V

• AC coupled AF stage

• AF operational amplifier output with offset compensated input stage

• High AF output voltage with low distortion

• High ripple rejection

• Low switching noise between AF and mute
