TDA4452
Video IF Amplifier for Multistandard TV Receiver and VTR
Appliances
Technology: Bipolar
Features
D Standard B/G-L suitable, processes negatively and
positively modulated IF-signals with equal polarity of
the output signal
D Ultra white inverter and ultrablack limiter for
reducing transmission interference
D Internally noise protected gain control, no flyback
pulses required
D Expanded video frequency response allows the
demodulation of amplitude modulated MAC signals
D High input sensitivity
D Minimal intermodulation distortions
D Small differential error
D Fast AGC by controlled discharge of the AGC
capacitor
D Standard L mode: AGC acting on peak white level,
capacitor discharge control by averaged video signal
Standard B/G: AGC acting on the sync. pulse peak
D Constant input impedance
D Video output voltage with narrow tolerance
D Video input/output for insertion of external sound trap
D VTR input/output with video switch
D Adjustable, delayed AGC for the tuner
D ESD protected
Case: DIP18
