Small, Low Power, Ambient Light Photo Detect IC Eval Board


The ISL29101IROZ-EVALZ is an RoHS compliant evaluation board used to evaluate the ISL29101 low power ambient light-to-voltage optical sensor. The sensing range for this device is from 0.5Lux to 10kLux typically and the device has been optimized for use with a 100kΩ output scaling resistor (REXT). The device and the evaluation board will work from a 3V supply.

In normal operation, the ISL29101 is intended to be mounted behind a smoked glass/plastic bezel, which normally significantly attenuates received light. This low light optimized analog output sensor will typically saturate at full scale with an incident illumination of around 1500Lux, which is a fair deal lower than normal indoor ambient light conditions (2k to 10kLux).
