ISL4089, DC-Restored Video Amplifier

ISL4089 DC-Restored Video Amplifier The ISL4089 is complete DC-restored monolithic video amplifier sub-system.

It contains a high performance video amplifier and a nulling, sample-and-hold amplifier designed to establish a programmable DC output level.

When the HOLD logic input “0” is applied the DC restore function is active.

The sample-and-hold amplifier loop is closed and used to null the DC offset of the video amplifier.

This can occur during sync, or, at any time that a black level is expe
