Glossary 3

filter

A device that passes a signal or range of signals and eliminates all
others.

filter frequency

The user-selectable frequency for a digital filter.

full-scale

The magnitude of input over which normal operation is permitted.

full-scale range

The difference between the maximum and minimum specified analog
input values for a device.

gain drift

Change in full-scale transition voltage measured over the operating
temperature range of the module.

input data scaling

Data scaling that depends on the data format selected for a channel
configuration word. Scaling is selected to fit the temperature or
voltage resolution for your application.

input image

The input from the module to the controller. The input image contains
the module data words and status bits.

linearity error

Any deviation of the converted input or actual output from a straight
line of values representing the ideal analog input. An analog input is
composed of a series of input values corresponding to digital codes.
For an ideal analog input, the values lie in a straight line spaced by
inputs corresponding to 1 LSB. Linearity is expressed in percent
