ELECTRICAL CHARACTERISTICS (continued)
(Circuit of Figure 1; V
+85°C, unless otherwise noted.) (Note 3)
Note 1: Current variation is caused by the current source voltage changes.
Note 2: Measurement is with respect to 100% of the programmed LED output current.
Note 3: Specifications to -40°C are guaranteed by design, not production tested.
