There are three GND below in our system.

DGND

AGND

GND for the image sensor

(image sensor is CMOS with analog output)

 

Connection of GND is shown below.

Image sensor GND---AGND---DGND

 

ADC will receive the signal from the sensor.

Does GND of AD9257 better connected to either AGND or image sensorGND?

 

Thanks,
