PARAMETER DEFINITIONS

Resolution - The number of different output codes possible. Expressed as N, where 2

of available output codes.

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

allowable input signal. Units in dB’s.

Signal to Intermodulation Distortion - The ratio of the rms sum of two input signals to the rms sum

of all discernible intermodulation and harmonic distortion products.

Linearity Error - The deviation of a code from a straight line passing through the endpoints of the

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.

Units in %FS.

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).

Units in mV.

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

LSB). Units in mV.

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

middle transition lying on a straight line between actual positive full-scale and actual negative

full-scale.

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.
