® 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 corre
