I am a design using the AD5545.
Datasheet there a specification of the typical value as Input Resistance (Rref) in the "REFERENCE INPUT Parameters", but please tell us about the max / min values.
The data sheet says that the input resistance value of the reference voltage pin is 5 kΩ ±30%.
Apologies for the delay.
Let me check this internally and get back to you.
