EL4093C
300 MHz DC-Restored Video Amplifier
Features
High accuracy DC restoration for video Low supply current of 9 5 mA typ 300 MHz bandwidth 1500V ms slew rate 0 04% differential gain and 0 02 differential phase into 150X for NTSC 1 5 mV max restored DC offset Sample and hold amplifier with fast enable and low leakage TTL-compatible HOLD logic input
General Description
The EL4093C 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 b 40 C to a 85 C and is packaged in plastic 16-pin DIP and 16lead SOIC
Applications
Input amplifier in video equipment Restoration amplifier in video mixers
