TDA4445A规格书详情

Circuit Description

This circuit includes the following functions

 Three symmetrical and gain controlled wide band amplifier stages, which are extremely stable by quasi DC coupling without feedback

 Averaged AGC with discharge control circuit

 AGC voltage generator

Quasi parallel sound operation

 High phase accuracy of the carrier signal processing, independent from AM

 Linear quadrature demodulator

 Sound–IF–amplifier stage with impedance converter

AM–Demodulation (TDA4445B only)

 Carrier controlled demodulator

 Audio frequency stage with impedance converter

 Averaged low pass AGC

特性 Features

 Very high input sensitivity

 Excellent signal to noise ratio

 Fast averaged AGC

 IF amplifier can be switched off for VTR mode

 Output signal stabilized against VSvariations

 Very few external components

TDA4445B additional

 Targeting bistandard applications (B/G and L)

 Alignment free AM demodulator

 Low AM distortion
