(1) The deviation of each output from the average of OUT0–OUT23 constant-current. Deviation is calculated by the formula:
(2) The deviation of the OUT0–OUT23 constant-current average from the ideal constant-current value. Deviation is calculated by the
following formula:
(3) Line regulation is calculated by this equation:
(4) Load regulation is calculated by the equation:
(5) Not tested. Specified by design.
