Small, Low Power, Current-Output Ambient Light Photo Detect IC

The ISL29006 is a 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. The ISL29006 offers an EN pin that can be used for a polling scheme to extend the battery life of portable devices. Housed in an ultra-compact 2mm x 2.1mm ODFN clear plastic package, this device is excellent for power saving control function in cell phones, PDAs and other handheld applications.
