AD7792 Configuration

Question asked by ap00 on Jun 6, 2014

We are trying to use the burnout current sources to detect when the connected TC is open.  We set up the ADC to convert the incoming TC signal.  After successful completion of this conversion we turn on the burnout current with the same settings.  By the chip document we should get full scale reading on the second conversion.  We are not.  Our filter circuit may be getting in the way not sure?
