TDA4439

TELEFUNKEN Semiconductors

Video IF Amplifier for Multistandard TV and VTR

Technology: Bipolar

Features

Standard B/G-L suitable, processes negatively and

positively modulated IF-signals with equal polarity of

the output signal

High input sensitivity

FastAGCbycontrolleddischargeoftheAGCcapacitor

Ultra white inverter and ultra black limiter for reduc-

ing transmission interference

Standard L mode: AGC acting on peak white level,

capacitor discharge control by averaged video signal

Internally noise protected gain control, no flyback

pulses required

Standard B/G: AGC acting on the sync. pulse peak

The direction of the AFC curve is selectable indepen-

dently from the standard switch

Expanded video frequency response allows the de-

modulation of amplitude modulated MAC signals

Case: DIP18
