Hello TI Team ,
We are using OPT3004 ALS in multiple project with 850 and 940 ir LED wavelength .
Case 1 : In Open Setup with IR850
1. Before IR LED Turn ON --- ALS Count is 24
2. After IR LED Turn ON-----ALS Count is 30
So this change in ALS count we corrected by putting gasket so with mechanical setup difference is very less .
Case 2 : In Open Setup with IR940
1. Before IR LED Turn ON --- ALS Count is 24
2. After IR LED Turn ON-----ALS Count is 0
So this change in ALS count we corrected by putting gasket so with mechanical setup difference is very less .
But we want to know why the ALS count is going down incase of 940 IR with IR leakage is high .
