[a] For ALS, the maximum duty cycle is selected with a 100ms measurement time (default) and 100ms repeat rate at an illumination of 1000 lux.

[b] For UVBS, the maximum duty cycle is selected with 100ms measurement time (default), 100ms repeat rate.

[c] Values valid up to 60°C.

[d] Typical timing accuracy applied.

[e] All specifications related to timing can vary by this value; for example, a repeat rate of 50ms could vary up to 62.5ms.
