Application Information
Light-to-Voltage Conversion
The ISL29102 has responsiveness that is a square-root
function of the light intensity intercepted by the photodiode in
lux. Because the photodiode has a responsivity that
resembles the human eye, conversion rate is independent of
the light source (fluorescent light, incandescent light or direct
sunlight).

Optical Sensor Location Outline
The green area in Figure 18 shows the optical sensor
location outline of ISL29102. Along the pinout direction, the
center line (CL) of the sensor coincides with that of the
packaging. The sensor width in this direction is 0.39mm.
Perpendicular to the pinout direction, the CL of the sensor
has an 0.19mm offset from the CL of packaging away from
pin 1. The sensor width in this direction is 0.46mm.
