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 expected. When the HOLD input “1” is applied, the
correcting voltage is stored on the video amplifier’s input
coupling capacitor. This condition must be true during active
video. The restored DC voltage level can be adjusted using
an external reference voltage applied to the V
The device operates from a single +5V supply and is ideal
for +5V only systems when used with a sync separator, such
as the EL1883.
The ISL4089 is intended to directly replace the EL4089 only
in certain applications. This direct replacement requires that
the single positive supply is no higher than +5.5V and that no
part of the clamped output goes below ground. The NC on
pin 6 is not internally connected, so it can be connected to
the -5V pin in existing EL4089 applications.
The ISL4089 is specified for operation over -40°C to +85°C
temperature range.
