Datasheet (ADuCM320 page 6) stated that Input current is 200uA typical.
But, could you please let me know the "Max value" of Input current? Is there any estimated value?
Two or three times seem ok, but we have no data to guarantee that. You can find the System Reference Voltage Block Diagram on Page 27 of ADuCM320 Hardware Reference Manual (UG-498) - Rev A.
I will be looking for the Min and Max values for the External Reference Input Current. This is not tested in volume testing, only a number of samples are characterized for the typical value.
Thank you for your response. understood.
How much should it assume the margin we expected? Twice or three times is OK?
And, it will be greatly appreciate it, if you could share the system reference black diagram?
