BLOCK DIAGRAM

Notes

(1) Light source: white LED

(2) Maximum detection range to ambient light can be determined by ALS refresh time adjustment. Refer to table 17 “ALS Resolution and

Maximum Detection Range”

(3) Based on IRED on / off duty ratio = 1/160, 1/320, 1/640, and 1/1280. The circuitry should use an external MOSFET as shown with Fig.11.
