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.
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
specifications for Current Sense Absolute Accuracy).
These are absolute values to be used when converting ADC codes to voltage readings; any inaccuracy in these values are factored into voltage accuracy values (see
specifications for Voltage Sense Accuracy).
Time between the receipt of the command byte and the actual ADC result being placed in the register.
Guaranteed by design; not production tested.
