Monitoring accuracy is a measure of the error in a code that is read back for a particular voltage/current. This is a combination of amplifier error, reference error, ADC
error, and error in ADC full-scale code conversion factor.
2
This is an absolute value to be used when converting ADC codes to current readings; any inaccuracy in this value is factored into absolute current accuracy values (see the
Specifications for the Current Sense Absolute Accuracy parameter).
3
These are absolute values to be used when converting ADC codes to voltage readings; any inaccuracy in these values is factored into voltage accuracy values (see the
Specifications for the Voltage Sense Accuracy parameter).
4
Time between the receipt of the command byte and the actual ADC result being placed in the register.
