EL4093
300MHz DC-Restored Video Amplifier
The EL4093 is a complete DC-
restored video amplifier subsystem,
featuring low power consumption and
high slew rate. It contains a current feedback amplifier and a
sample and hold amplifier designed to stabilize video
performance. When the HOLD logic input is low, the sample
and hold may be used as a general purpose op amp to null
the DC offset of the video amplifier. When the HOLD input
goes high the sample and hold stores the correction voltage
on the hold capacitor to maintain DC correction during the
subsequent video scan line.
The sample and hold amplifier contains a current output
stage that greatly simplifies its connection to the video
amplifier. Its high output impedance also helps to preserve
video linearity at low supply voltages. For ease of interfacing,
the HOLD input is TTL-compatible. This device has an
operational temperature of -40°C to +85°C and is packaged
in plastic 16-pin DIP and 16-pin SOIC.
