Figure 44 of the PGA280 datasheet indicates two current sources for wire break diagnostics.
IF I want to keep these current sources active all the time to be able to continuously monitor the wire condition will this have an impact on the noise performance of the device?
Will the permanent activation of the current sources have an impact on the offset and drift?
I understand the PGA has a zero drift PGA. How is this done?
Does it menas there is also no 1/f noise and does the zero drift also compensates for imbalance between the two current sources?
