2 Functional description
This section gives an overview of the key features of the VL6180X and describes the
different modes of operation of the ALS and proximity sensors.
Typical ranging performance of the VL6180X is shown in Figure 6. This demonstrates the
reflectance independence and range accuracy of the VL6180X from 0 to 100 mm for 3%,
5%, 17% and 88% reflective targets. The example shown here is with ST cover glass and a
1.0 mm air gap.
Figure 7 shows typical ALS linearity vs gain over a wide dynamic range. More details about
the ambient light sensor can be found in Section 2.13.
