QI would like to know what is the use of the burnout current in the AD7787.
AThe burnout currents are there to be used generally before a conversion, to see
if the sensor is still present. It can be used for detecting short or open
sensor inputs. It's not like a flag or an interrupt though, the user has to
enable the current sources and then perform a measurement and look to see if
the measurement is the expected measurement.
