      Hi Kou, Thank you for giving additional information about your application. I believe that in video switching, you should use an amplifier that has high input impedance, high bandwidth and high output current drive. With this specification, I recommend the following amplifier products which has an excellent video specification: ADA4850 …

      Hi Kou, I checked our Opamp portfolio and you may want to consider the ADA4861-3 and ADA4850-2 which are both video amplifiers. I still encourage you to specify your opamp requirement (ie, bandwidth, power supply, slew rate...) so we can choose the best option for your application …
