USERS MANUAL ISL29101IROZ-EVALZ, ISL29102IROZ-EVALZ, ISL29112IROZ-EVALZ UG056 Evaluation Boards Rev.1.00 Sep 13, 2018 Description Hardware Setup ISL29101, ISL29102, and ISL29112 are low-ight optimized Each evaluation board comprises the sensor device and a analog output sensors. This user guide is for the evaluation 100k resistor that sets the output scaling for the sensor. The boards: ISL29101IROZ-EVALZ, ISL29102IROZ-EVALZ, and parts were characterized with the 100k resistor. Larger or ISL29112IROZ-EVALZ. smaller values can be used however, Renesas found that the 100k value worked well under a variety of conditions. Note In normal operation, these sensor devices are intended to be that with larger scale setting resistors, the sensor is likely to mounted behind a smoked glass/plastic bezel, which normally prematurely saturate at relatively low light levels. significantly attenuates received light. The ISL29101 and ISL29102 typically saturate at full scale with an incident The jumpers and components on the Printed Circuit Board illumination of around 10,000Lux. However, the ISL29112 has (PCB) are as listed in Table 1. a range up to 100Lux, which is a lower than normal indoor TABLE 1. JUMPERS, COMPONENTS ON PCB ambient light condition (2k to 10kLux). JUMPER DESCRIPTION The ISL291xxIROZ-EVALZ evaluation board are RoHS-compliant evaluation boards prepared to speed up part JP2 R = 100k LOAD (Optional, Do not populate) evaluation. The device and the evaluation boards work from a 3V supply. JP3 R = 1k LOAD (Optional, Do not populate) Note that each device has a different scaling factor relative to incident ambient light. Please refer to the part datasheet for JP4 R = 10M LOAD converting output voltage to light intensity.
