Intersil introduces ultra-low lux digital ambient light sensor

Intersil has released an ultra-low lux ambient light sensor, the ISL29033 with linear sensitivity to 0.0019 lux, The ISL29033 is an integrated ambient and infrared light-to-digital converter with an SMBus compatible I2C interface. Its advanced, self-calibrated photodiode array emulates human eye response with excellent IR rejection. The on-chip 16-bit ADC is capable of rejecting 50 Hz and 60 Hz flicker caused by artificial light sources. The lux-range-select feature allows users to program the lux range to optimize counts/lux for specific applicaitons. The light-to-digital converter draws 55 ?A in operation; less than 300 nA in power-down mode.The ISL29033 supports a software and hardware interrupt that remains asserted until the host clears it through the I2C interface. The function of ADC conversion continues without stopping after interrupt is asserted. Operating on supplies from 2.25 to 3.63 V with an I2C supply from 1.7 to 3.63 V, the ISL29033 is specified for operation over the -40 °C to +85 °C ambient temperature range. Among the applications are display and keypad dimming adjustment for mobile devices such as smartphones and personal navigation devices, computing notebooks and tablets and consumer LCD TVs, digital picture frames, and cameras as well as industrial and medical light sensing uses. The ISL29033 is available in a 6-Lead 2.0 x 2.1 x 0.7 mm ODFN package. Prices start at $1.31 (1,000). www.intersil.com Intersil Ambient Light Sensors deep-link
