1 digital red, green and blue color light sensor with ir blocking filter ISL29125 the ISL29125 is a low power, high sensitivity, red, green, and blue color light sensor (rgb) with an i 2 c (smbus compatible) interface. its state-of-the-art photodiode array provides an accurate rgb spectr al response and excellent light source to light source variation (ls2ls). the ISL29125 is designed to reject ir in light sources allowing the device to operate in environments from sunlight to dark rooms. the integrating adc rejects 50hz and 60hz flicker caused by artificial light sources. a selectable range allows the user to optimize sensitivity suitable for the specific application. in normal operation mode the device consumes 56a which reduces to 0.5a in power down mode. the ISL29125 supports hardware and software user programmable interrupt thresholds. the interrupt persistency feature reduces false trigger notification. the device operates on supplies (vdd) from 2.25v to 3.63v, i 2 c supply from 1.7v to 3.63v, and operating temperature over the -40c to +85c. features ? 56a operating current, 0.5a shutdown current ? selectable range (via i 2 c) ?i 2 c (smbus compatible) output ? adc resolution 16 bits ? programmable interrupt windows ? two optical sensitivity ranges - range 0 = 5.7m lux to 375 lux - range 1 = 0.152 lux to 10,000 lux ? operating power supply 2.25 to 3.63v ?i 2 c power supply 1.7v to 3.63v ? 6 ld odfn (1.65x1.65x0.7mm) package applications ? smart phone, pda, gps, tablet pcs, lcd-tvs, digital picture frames, digital cameras ? dynamic display color balancing ? printer color enhancement ? industrial/commercial led lighting color management ? ambient light color detection/correction ? oled display aging compensation figure 1. typical application diagram ISL29125 mcu scl sda 4 6 1 3 5 vdd gnd scl sda gpio int vbus 2 nc r2 r3 r4 vdd r1 c1 c2 r1 ? 100 r2 ? 2.7k to 10k r3 ? 2.7k to 10k r4 ? 2.7k to 10k c1 ? 1f c2 ? 0.1f caution: these devices are sensitive to electrostatic discharge; follow proper ic handling procedures. 1-888-intersil or 1-888-468-3774 | copyright intersil americas llc 2013. all rights reserved intersil (and design) is a trademark owned by intersil corporation or one of its subsidiaries. all other trademarks mentioned are the property of their respective owners. november 20, 2013 fn8424.0
