Resolution - N

The number of different output codes possible. Expressed as N, where 2N is the number of

available output codes.

Noise -

A measure of the variability of the converter’s output when a fixed DC input (usually ground)

is applied to the input and a large number of samples are taken. RMS noise is determined

statistically as the Standard Deviation of the Probability Density Function derived from the

histogram of the ADC with the differential inputs shorted together and tied to an appropriate

common mode voltage.

Common Mode Rejection Ratio - CMRR

A measure of the device’s ability to cancel out the effect of a common voltage applied to both

of its differential inputs. CMRR is specified as the ratio of the differential signal gain to the

gain for the common-mode signal. Units in dB.

Offset Drift -

Changes in the offset error of the part after self calibration due to changes in ambient

temperature. Specified in microvolts per degree C, relative to the input signal.

Full Scale Drift -

Changes in the full scale error of the part after self calibration due to changes in ambient

temperature. Specified in parts-per-million (PPM) of the full scale range per degree C.
