DC Restored Video Amplifier
video amplifier and a nulling, sample-and-hold amplifier
specifically designed to stabilize video performance.
When the HOLD logic input is set to a TTL/CMOS logic 0,
the sample - and - hold amplifier can be used to null the DC
offset of the video amplifier.
When the HOLD input goes to a TTL/CMOS logic l, the
correcting voltage is stored on the video amplifier’s input
coupling capacitor. The correction voltage can be further
corrected as need be, on each video line.
The video amplifier is optimized for video performance and
low power. Its current feedback design allows the user to
maintain essentially the same bandwidth over a gain range
of nearly 10:1. The amplifier drives back-terminated 75Ω
lines.
The EL4089 is fabricated in Elantec’s proprietary
Complementary Bipolar process which produces NPN and
PNP transistors with equivalent AC and DC performance.
The EL4089 is specified for operation over -40°C to +85°C
temperature range.
Pinout
DC Restoring Amplifier with a gain of 2, restoring to ground
The EL4089 is an 8-pin complete DC-
restored monolithic video amplifier
sub-system. It contains a high quality
(8-PIN PDIP, SO)
