ISL29102 Application Information ISL29102's output circuit may result in premature saturation when an excessively large REXT is used. The output compliance Light-to-Voltage Conversion voltage is 700mV below the supply voltage as listed in VO-MAX of the “Electrical Specifications” table on page3. The ISL29102 has responsiveness that is a square-root function of the light intensity intercepted by the photodiode in lux. Optical Sensor Location Outline Because the photodiode has a responsivity that resembles the The green area in Figure19 shows the optical sensor location human eye, conversion rate is independent of the light source outline of ISL29102. Along the pinout direction, the center line (fluorescent light, incandescent light, or direct sunlight). (CL) of the sensor coincides with that of the packaging. The V = ----1---.--8--------A------ ER (EQ. 1) sensor width in this direction is 0.39mm. Perpendicular to the OUT 100lux EXT 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 In Equation1, VOUT is the output voltage, E is the light intensity, direction is 0.46mm. and REXT is the value of the external resistor.
