General Description
The EL4089C is an 8-pin complete DC-restored monolithic vid-
eo amplifier sub-system It contains a high quality video ampli-
fier and a nulling sample-and-hold amplifier specifically de-
signed to stabilize video performance
When the HOLD logic input is set to a TTLCMOS 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 TTLCMOS logic l the cor-
recting 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 101
The amplifier drives back-terminated 75
X lines
The EL4089C is fabricated in Elantec’s proprietary Comple-
mentary Bipolar process which produces NPN and PNP tran-
sistors with equivalent AC and DC performance The EL4089C
is specified for operation over 0 Cto a75 C temperature range
