I am layouting ad5410, but i have a question about the eleventh pin of AD5410.Do i need to connect it to the anolog gnd? Or it is the output reference gnd.
Are you using the TSSOP package (AD5410AREZ)? if yes, pin 11 should be connected to ground. This pin as well as the other GND pins are the ground reference for the AD5410.
If you are using the LFCSP package (AD5410ACPZ), pin 11 should be left floating.
