TMD3702VC − Electrical Characteristics

Figure 8:

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

Figure 9:

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

Note(s):

1. Test condition integration time = 27.8ms.

2. Representative result by characterization.

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