TDA4439
Video IF Amplifier for Multistandard TV and VTR
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 ultra black limiter for reduc-
ing transmission interference
D Internally noise protected gain control, no flyback
pulses required
D Expanded video frequency response allows the de-
modulation of amplitude modulated MAC signals
D High input sensitivity
D Fast AGC by controlled discharge of the AGC capacitor
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 The direction of the AFC curve is selectable indepen-
dently from the standard switch
Case: DIP18
Rev. A1: 14.09.1995
