EL4093

300MHz DC-Restored Video Amplifier

DATASHEET

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.
