Each PCIM-DAS1602/16 is tested at the factory to assure the board’s overall error does not exceed ±5 LSB.
Total board error is a combination of gain, offset, differential linearity and integral linearity error. The
theoretical absolute accuracy of the board may be calculated by summing these component errors. Worst caseerror is realized only in the unlikely event that each of the component errors are at their maximum level, andcausing error in the same direction.

Absolute error change per °C Temperature change is a combination of the gain and offset drift of manycomponents. 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 theirmaximum level, and causing error in the same direction.

Noise performance
The following table summarizes the worst case noise performance for the PCIM-DAS1602/16. Noise
distribution is determined by gathering 50000 samples with inputs tied to ground at the PCIM-DAS1602/16
main connector. Data is for both Single-Ended and Differential modes of operation.

Specifications

Crosstalk
Crosstalk is defined here as the influence of one channel upon another when scanning two channels at thespecified per channel rate for a total of 50000 samples. A full scale 100Hz triangle wave is input on channel 1.
channel 0 is tied to analog ground at the 100 pin user connector. The table below summarizes the influence ofchannel 1 on channel 0 and does not include the effects of noise.
