Integral nonlinearity error (INL)

Integral nonlinearity error is the maximum deviation between the ideal output voltage based on the ideal conversion

characteristic when the measured offset and full-scale errors are zeroed, and the actual output voltage.

Differential nonlinearity error (DNL)

Differential nonlinearity error is the difference between 1-LSB voltage width based on the ideal D/A conversion

characteristics and the width of the actual output voltage.

Offset error

Offset error is the difference between the highest actual output voltage that falls below the lower output limit and the ideal

output voltage based on the input code.

Full-scale error

Full-scale error is the difference between the lowest actual output voltage that exceeds the upper output limit and the ideal

output voltage based on the input code.
