Richie,
There are many indications in the data sheet that the REF pin is an output. Some data sheets can be
16, 24, or over 100 pages long. The only thing that counts in a court of law is the spec table. That is
what we are selling. The spec table says REF and REFIN are BOTH outputs and even give you the
voltage you should measure.
In addition to that, the pin function table says both pins can be inputs or outputs.
Where is the confusion?
