Notes:

(1) Ensured by design and characterization, not production tested

(2) LED current matching for 8 channels is defined as the largest of the two numbers, i.e., (MAX-AVG)/AVG and (AVG-MIN)/AVG; where MAX is the

maximum of LED channel current, MIN is the minimum LED channel current and AVG is the average of the 8 LED channel current.

(3) Refer to the detailed application circuit on page 21.
