Description
The NOA1211 is a very low power ambient light sensor (ALS) with an analog current output and a power down mode to conserve power. Designed primarily for handheld device applications, the active power dissipation of this chip is less than 8 A at dark and its quiescent current consumption is less than 200 pA in power down mode.

FEATUREs
• Senses Ambient Light and Provides an Output Current Proportional to the Ambient Light Intensity
• Photopic Spectral Response
• Dynamic Dark Current Compensation
• Two Selectable Output Current Gain Modes
• Power Down Mode
• Less than 18 A at 100 lux Active Power Consumption in Normal Operation (Less than 8 A at Dark)
• Less than 200 pA Quiescent Power Dissipation in Power Down Mode at All Light Levels
• Linear Response Over the Full Operating Range
• Senses Intensity of Ambient Light from ~0 lux to Over 100,000 lux
• Wide Operating Voltage Range (2 V to 5.5 V)
• Wide Operating Temperature Range (−40°C to 85°C)
• Drop−in Replacement Device in 1.6 x 1.6 mm Package
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Compliant
