General 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.
