1
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 the 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
Time between the receipt of the command byte and the actual ADC result being placed in the register.
4
Guaranteed by design; not production tested.
