My part has startup problems during Power Up
This startup issue looks like that described in the attached note as symptom no
2. The solution is to reduce the capacitive load and/or add a resistive load
to avoid restart issues, as shown in figure 1. There is a revision that is
available through distribution, with data code 11/28 or later.
Please see the symptoms in the attached document
This applies to all ADuM52xx and All ADuM64xx parts
There is a new die available which was introduced mid 2011 - please see
