(2)

The deviation of each output from the average of OUT0 to OUT15 constant-current. Deviation is calculated by the formula:

.

(3)

The deviation of the OUT0 to OUT15 constant-current average from the ideal constant-current value. Deviation is calculated by the

formula:

Ideal current is calculated by the formula:
