DATASHEET ISL29006, ISL29007, ISL29008 FN6282 Rev 2.00 Small, Low Power, Current-Output Ambient Light Photo Detect IC October 8, 2015 The ISL29006, ISL29007, and ISL29008 are light-to-current Features silicon optical sensors combining a photodiode array and a 0.5 lux to 10,000 lux range current amplifier on a single monolithic IC. The photodiodes spectral sensitivity approximates the human eye response 1.8V to 3.6V supply range peaking at 550nm with virtually no infrared (IR) response. Low supply current (3.5A 100 lux) Exposed to light, these light sensors give current outputs Fast response time that are linearly proportional to the light intensity. The output Close to human eye response of ISL29006 is configured as a current source, and the output of ISL29007 is configured as a current sink. Both IR Rejection ISL29006 and ISL29007 offer an EN pin that can be used for Internal dark current compensation a polling scheme to extend the battery life of portable devices. Lux to current source or/and sink The ISL29008 has dual outputs simultaneously sinking and Excellent output linearity of luminance sourcing current. With output currents at opposite polarity, it 6 Ld ODFN: 2mmx2.1mmx0.7mm can simultaneously control two light sources/drivers that Pb-free (RoHS compliant) have incongruent illumination requirement depending on ambient light conditions. For example, at bright ambient light Applications levels, display backpanels need more intensity while the keyboard illumination needs to be dimmer, whereas at Display and keypad dimming for: darker ambient light levels, display backpanels need less - Mobile devices: smart phone, PDA, GPS intensity while the keyboard illumination needs to be - Computing devices: notebook PC, webpod brighter. - Consumer devices: LCD-TV, digital picture frame, digital By connecting an external resistor from ISRC to GND or camera from ISNK to VDD, the current output can be converted into Industrial and medical light sensing voltage output. Housed in an ultra-compact 2mmx2.1mm ODFN clear Ordering Information plastic package, this device is excellent for power saving TEMP. control function in cell phones, PDAs and other handheld PART NUMBER RANGE PACKAGE PKG. applications.
