(1) The deviation of each output in the same color group (OUTR0-OUTR3 or OUTG0-OUTG3 or OUTB0-OUTB3) from the average current
from the same color group. Deviation is calculated by the formula:
Where: X = R/G/B, and n = 0-3
(2) The deviation of each color group constant-current average from the ideal constant-current value.
Deviation is calculated by the following formula:
Where: X = R/G/B.
Ideal current is calculated by the following formula for the OUTRn and OUTGn groups:
Where: X = R/G/B.
(3) Line regulation is calculated by this equation:
Where: X = R/G/B, n = 0-3.
(4) Load regulation is calculated by the equation:
Where: X = R/G/B, n = 0-3.
(5) Not tested, specified by design.
