TMG49037 − Electrical Characteristics

Figure 8:

ALS/Color Operating Characteristics, VDD = 1.8 V, TA = 25ºC, AGAIN = 16x, ATIME = 0xF6 (unless

otherwise noted)

Note(s):

1. Integration time is configured from 1 step (0xFF) to 256 steps (0x00) for a typical range of 2.78ms to 711.11ms. An ATIME setting of

0xFF results in a full-scale count value of 1024. Each additional integration step adds 1024 counts to full scale. To enable 16-bit ADC

range, 64 or more integration steps (177.8ms or more) are required (ATIME <= 0xC0).

2. The typical 3-sigma distribution is between 0 and 1 count for an AGAIN setting of 16x.

3. Lux accuracy is function of red, green, blue and clear channels, and not 100% production tested.

4. ADC noise is calculated as the standard deviation of 1000 data samples.
