EL4089

Overview
® Data Sheet July 1998, Rev C EL4089 FN7158 DC Restored Video Amplifier The EL4089 is an 8-pin complete DCrestored monolithic video amplifier sub-system.
It contains a high quality 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.
