(1)

The electrical characteristics tables list ensured specifications under the listed recommended conditions except as otherwise modified or

specified by the electrical characteristics test conditions and/or notes. Typical specifications are estimations only and are not verified by

production testing.

(2)

All voltages are with respect to the potential at the GND pins.

(3)

Minimum and maximum limits are ensured by design, test, or statistical analysis. Typical numbers are not verified by production, but do

represent the most likely norm.

(4)

Output current accuracy is the difference between the actual value of the output current and programmed value of this current. Matching

is the maximum difference from the average. For the constant current outputs on the part, the following are determined: the maximum

output current (MAX), the minimum output current (MIN), and the average output current of all outputs (AVG). Two matching numbers

are calculated: (MAX – AVG)/AVG and (AVG – MIN)/AVG. The largest number of the two (worst case) is considered the matching

figure. Note that some manufacturers have different definitions in use.

(5)

Saturation voltage is defined as the voltage when the LED current has dropped 10% from the set value.
