DUAL VIDEO 6dB AMPLIFIER

WITH 75Ω DRIVER

 DESCRIPTION

The UTC V2267 is a dual video 6dB amplifier with 75drivers

for SVHS VCRs, HI-BAND VCRs, etc. Its operating supply voltage is

4.85 to 9V and bandwidth is 7MHz. Each channel has clamp function

that fixes DC level of video signal and 75 drivers to be connected

to TV monitors directly. Further more it has SAG corrective circuits

that prevent the generation of SAG with a small capacitance.

It is for VCR, Video Camera, TV, Video Disc Player.

 FEATURES

* Dual Channel

* Wide Operating Voltage (4.85V ~ 9.0V)

* Low Operating Current 14.0mA (Dual)

* Wide Frequency Range (7MHz)

 APPLICATION

Oscillation Prevention

It is much effective to insert LPF (Cutoff Frequency 70MHz) under light loading conditions (RL>>1k)

This IC requires 1M resistance between INPUT and GND pin for clamp type input since the minute current

causes an unstable pin voltage.
