Thread Summary

                The user inquired about the SDNn pin of the AD8465: 1) It should be driven to a valid logic level (VIL ≤ 0.6V for shutdown, VIH ≥ 2.0V for normal operation) and not left floating. 2) SDN is referenced to VCCO, with its high-level specification extending up to VCCO and input-high current specified at VIH = VCCO.

The AD8465 datasheet does not seem to say much about the SDNn pin. I would like to know two things:


1. Is it internally pulled up? Or does it always need a valid level?


2. Is it referred to VCCO? 
The Absolute Maximum Ratings show SDNn as having a max voltage of "VCCO + 0.5 V ", but the diagram on first page shows it connected to the input comparator.


Thanks!
