General Description
The EL4093C is a complete DC-restored video amplifier subsys-
tem 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 am-
plifier 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
b40 C to a85 C and is packaged in plastic 16-pin DIP and 16-
lead SOIC
