Note 8: .Junction-to-ambient thermal resistance is highly application and board-layout dependent. In applications where high maximum power dissipation exists,
special care must be paid to thermal dissipation issues in board design.
Note 9: Min and Max limits are guaranteed by design, test, or statistical analysis. Typical numbers are not guaranteed, but do represent the most likely norm.
Note 10: Matching is the maximum difference from the average.
Note 11: The current source is connected internally between V
an V
. The voltage across the current source, (V
- V
), is referred to a Headroom Voltage

(V
). Minimum Headroom Voltage is defined as the V
voltage when the LED current has dropped 20% from the value measured at V
= V
- 1V.
