UTC TA7611AP LINEAR INTEGRATED CIRCUIT
FM IF/AM TUNER SYSTEM
DESCRIPTION
The UTC TA7611AP is a monolithic integrated circuit, designed for the VIF stage in color and B/W TV receiver. The UTC TA7611AP is used for Forward AGC type.
FEATURES
*High gain wide brand IF amplifier *Gain reduction with excellent stability *Excellent DG/DP and S/N characteristics *Negative video output signal *Fast AGC action due to noise inverter and peak AGC *Switch off the video part VTR SW
FUNCTIONS
*Three controlled IF amplifier stages *Video demodulator controlled by picture carrier *Black noise and white noise inverter *Peak AGC *DC amplifier for RF AGC output *Quadrature detector for AFT *DC amplifier for AFT
