Note 1:
Output matching is calculated as the percent variation from (I

)/2.
Note 2:
With a fixed resistor on the brightness input pin some variation in brightness will occur from one device to another. Maximum brightness input current can
be 2 mA as long as Note 3 and junction temperature equation are complied with.
Note 3:
Absolute maximum for each output should be limited to 40 mA.
Note 4:
The V
