PARAMETER DEFINITIONS
Resolution - The number of different output codes possible. Expressed as N, where 2
Dynamic Range - The ratio of the largest allowable input signal to the noise floor.
Total Harmonic Distortion - The ratio of the rms sum of all harmonics to the rms value of the largest
Signal to Intermodulation Distortion - The ratio of the rms sum of two input signals to the rms sum
Linearity Error - The deviation of a code from a straight line passing through the endpoints of the
Differential Nonlinearity - The deviation of a code’s width from the ideal width. Units in LSB’s.
Positive Full Scale Error - The deviation of the last code transition from the ideal, (VREF - 3/2 LSB).
Positive Full Scale Drift - The drift in effective, positive, full-scale input voltage with temperature.
Negative Full Scale Error - The deviation of the first code transition from the ideal, (-VREF + 1/2
Negative Full Scale Drift - The drift in effective, negative, full-scale input voltage with temperature.
Bipolar Offset - The deviation of the mid-scale transition from the ideal. The ideal is defined as the
Bipolar Offset Drift - The drift in the bipolar offset error with temperature.
Absolute Group Delay - The delay through the filter section of the part.
Passband Frequency - The upper -3 dB frequency of the CS5317.

transfer function after zero- and full-scale errors have been accounted for. "Zero-scale" is a
point 1/2 LSB below the first code transition and "full-scale" is a point 1/2 LSB beyond the
code transition to all ones. The deviation is measured from the middle of each particular code.
