Description

The EL4089C is an 8-pin complete DC-restored 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 amplifer.


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 75 lines.

The EL4089C is fabricated in Elantec's proprietary Complementary Bipolar process which produces NPN and PNP transistors with equivalent AC and DC performance. The EL4089C is specified for operation over 0ßC to a75ßC temperature range.
