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
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
