TDA3843中文资料Sound-IF circuit for TV AM-sound standard L and L’数据手册恩XP规格书

描述 Description

GENERAL DESCRIPTION
The TDA3843 performs the AM-sound demodulation for the L- and L’-standard.

特性 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
• Reduced THD figures even for low AF frequencies (typical 1%)
• Stabilizer circuit for ripple rejection and constant output signals
• All pins are ESD protected
