LINEAR INTEGRATED CIRCUIT
DUAL VIDEO 6dB AMPLIFIER
WITH 75Ω DRIVER
DIP-8

DESCRIPTION
The UTC V2267 is a dual video 6dB amplifier with 75Ω 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 75Ω 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.


LINEAR INTEGRATED CIRCUIT
APPLICATION
Oscillation Prevention
It is much effective to insert LPF (Cutoff Frequency 70MHz) under light loading conditions (RL>>1kΩ)
This IC requires 1MΩ resistance between INPUT and GND pin for clamp type input since the minute current
causes an unstable pin voltage.
