Description

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 n plastic 16-pin DIP and 16-pin SOIC.
