Autonomous ranging mode

5.3.1

Measurement conditions

The following criteria and test conditions apply to all the characterisation results detailed in this section unless

specified otherwise:

•

The specified target fills 100 % of the field of view of the device (in all zones).

•

Targets used are Munsell N4.75 (17 %) and Munsell N9.5 (88 %).

•

AVDD is 2.8 V, IOVDD is 1.8 V.

•

•

Maximum range capability is based on a 90 % detection rate (1).

•

Range accuracy figures are based on 2.7 sigma ie 99.3 % of measurements are within the specified

accuracy.

•

940 nm is equivalent to 5 kLux daylight.

•

All tests are performed without coverglass.

•

The sensor relies on default calibration data.

•

The device is controlled thought the API using the default driver settings.

1. Detection rate is a statistical value indicating the worst case percentage of measurements that return a valid ranging. For

example, taking 1000 measurements with 90 % detection rate gives 900 valid distances. The 100 other distances may be

outside the specification.
