Gain Error

Total board error is a combination of Gain, Offset, Integral Linearity and Differential
Linearity error. The theoretical worst-case error of the board may be calculated by
summing these component errors. Worst case error is realized only in the unlikely
event that each of the component errors are at their maximum level, and causing error
in the same direction. Each PC-CARD-DAC08 is tested at the factory to ensure the
board's overall SW calibrated error does not exceed ±4.0 LSB.
Typical accuracy is derived directly from the various component typical errors. This
typical error calculation for a SW calibrated PC-CARD-DAC08 yields ±1.8 LSB.

System-dependent. Using the Universal Library
programmed output function (cbAout) in a loop, in
Visual Basic, a typical update rate of 50 kHz
(±3kHz) can be expected. This rate was measured
on a 500 MHz Pentium III based PC running under
Windows 98.
