TMD3725 − Typical Operating Characteristics

Figure 8:

Optical Characteristics, VDD = 1.8V, TA = 25°C (unless otherwise noted)

Figure 9:

ALS Optical Characteristics, VDD = 1.8V, TA = 25°C (unless otherwise noted)

Note(s):

1. The typical value based on 3-sigma distribution. An AGAIN setting of 16x correlates to a typically dark ADC count value less than or

equal to 1.
