TDA3843 - NXP

TDA3843 Sound-IF circuit for TV AM-sound standard L and L

The TDA3843 performs the AM-sound demodulation for the L- and L’-standard. Features • 5 to 8 V power supply and an alternative 12 V power supply • Low power consumption (200 mW) at 5 V supply voltage • New AC-coupled wideband IF-amplifier (high dynamic ranges, less intermodulation) • In-phase wideband AM demodulator without external reference circuit • Reduc.

Features
