Definition of Specifications
Integral Linearity Error, INL, is the measure of the worst
case point that deviates from a best fit straight line of data
values along the transfer curve.
Differential Linearity Error, DNL, is the measure of the
step size output deviation from code to code. Ideally the step
size should be 1 LSB. A DNL specification of 1 LSB or less
guarantees monotonicity.
Feedthru is the measure of the undesirable switching noise
coupled to the output.
Output Voltage Full Scale Settling Time, is the time
required from the 50% point on the clock input for a full scale
step to settle within an ¹/₂ LSB error band.
Output Voltage Small Scale Settling Time, is the time
required from the 50% point on the clock input for a 100mV
step to settle within an ¹/₂ LSB error band. This is used by
applications reconstructing highly correlated signals such as
sine waves with more than 5 points per cycle.
Glitch Area, GE, is the switching transient appearing on the
output during a code transition. It is measured as the area
under the curve and expressed as a Volt-Time specification.
Differential Gain, ∆A_V, is the gain error from an ideal sine
wave with a normalized amplitude.
