Video Amplifier Simple Circuit Diagram with op-amp


Video Amplifier Simple Circuit Diagram with op-amp

Audio (power amp) and video amplifier in an electronic amplifier that strengthens low-power signal to a desired level for many audio video electronic devices.

Video amplifier has been used to amplify video signals from the video player and distribute to a television, radar, oscillographs, digital equipment and other equipment for video display or a cathode ray tube.

The schematic diagram shows a simple high speed op-amp applications by using  LH0032 to build a video amplifier circuit.

The LH0032 have an advantange of FET input characteristics and a very high speed general purpose operational amplifiers exhibiting 70 MHz bandwidths, 100 to 300 ns settling time to 0.1%. and  500 V/μs slew rates.
