I'm using OPA4872-EP as video multiplexer of 4*1.
I've two grounds.
1)- Digital ground.
2)- Analog Ground.
There are 04 inputs which are to be controlled by the microcontroller which is using digital ground. However, the video sources are with respect to Analog ground. Please confirm should the pins 2 (GND) and pin 4 (GND) are to be connected with the digital ground or analog ground? I think we need to connect with Digital ground and we don't need any connection with the analog ground.
