DATASHEET ISL29102 FN6483 Rev.2.00 Low Power Ambient Light-to-Voltage Nonlinear Converter Nov 17, 2016 The ISL29102 is a low cost, light-to-voltage silicon optical Features sensor combining a photodiode array, a nonlinear current Square root voltage output amplifier, and a micro-power op amp on a single monolithic IC. Similar to human eyes, the photodiode array has peak 0.3 lux to 10,000 lux range sensitivity at 550nm and spans from 400nm to 600nm, 1.8V to 3.3V supply range rejecting UV light and IR light. The input luminance range is Close to human eye spectral response from 0.3 lux to 10,000 lux. Fast response time The integrated nonlinear current amplifier boosts and converts the photodiode signal in a square root fashion, extending the Internal temperature compensation light input dynamic range, while maintaining excellent Good IR rejection sensitivity at dim conditions with low lux levels. The device Low supply current consumes minimal power over a wide range of ambient lux levels because the current consumption ramps at a square Operating temperature range -40C to +85C root fashion. A dark-current compensation circuit minimizes 6 Ld ODFN: 2mmx2.1mmx0.7mm the effect of temperature-dependent leakage currents in the Pb-free (RoHS compliant) absence of light, improving the light sensitivity at low lux levels while maintaining excellent sensitivity at low lux levels. The Applications built-in 1A op amp gives the ISL29102 an output voltage driving advantage for heavier loads. Display and keypad dimming for: - Mobile devices: smart phone, PDA, GPS The ISL29102 is housed in an ultra compact 2mmx2.1mm ODFN plastic case surface mount package. Operation is rated - Computing devices: notebook PC, webpod from -40C to +85C. - Consumer devices: LCD-TV, digital picture frame, digital camera Related Literature Industrial and medical light sensing For a full list of related documents, visit our website - ISL29102 product page VDD 1 VOUT - CURRENT 6 LIGHT DATA + AMPLIFIER PROCESS OUTPUT CURRENT LIGHT INTENSITY PHOTODIODE ARRAY GND 2 4 REXT FIGURE 1.
