TERMINOLOGY
Relative Accuracy
Relative accuracy or endpoint nonlinearity is a measure of the
maximum deviation from a straight line passing through the
endpoints of the DAC transfer function. It is measured after
adjusting for ideal zero and full scale and is expressed in % of
full-scale range or (sub) multiples of 1 LSB.
Resolution
Value of the LSB. For example, a unipolar converter with n bits
has a resolution of (2
a resolution of [2
linearity.
Settling Time
Time required for the output function of the DAC to settle to
within ½ LSB for a given digital input stimulus, that is, 0 to
full scale.

Gain Error
Gain error is a measure of the output error between an ideal
DAC and the actual device output. It is measured with all 1s in
the DAC after offset error is adjusted out and is expressed in LSBs.
Gain error is adjustable to zero with an external potentiometer.
Feedthrough Error
Error caused by capacitive coupling from V
