EL4089CS

直流恢复视频放大器 DC Restored Video Amplifier

The EL4089 is an 8-pin complete DC restored monolithic video amplifier sub-system. It contains a high quality

video amplifier and a nulling, sample-and-hold amplifier specifically designed to stabilize video performance. When the HOLD logic input is set to a TTL/CMOS logic 0, the sample - and - hold amplifier can be used to null the DC offset of the video amplifier.
