The ISL29006, ISL29007, and ISL29008 are light-to-current silicon optical sensors combining a photodiode array and a current amplifier on a single monolithic IC. The photodiode's spectral sensitivity approximates the human eye response peaking at 550nm with virtually no infrared (IR) response. Exposed to light, these light sensors give current outputs that are linearly proportional to the light intensity. The output of ISL29006 is configured as a current source, and the output of ISL29007 is configured as a current sink. Both ISL29006 and ISL29007 offer an EN pin that can be used for a polling scheme to extend the battery life of portable devices.
