Ambient Light Sensor with
Dark Current Compensation
Description
The NOA1213 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 mA at dark and its quiescent
current consumption is less than 200 pA in power down mode. The
device can operate over a very wide range of voltages from 2 V to
5.5 V. The NOA1213 employs proprietary CMOS image sensing
technology from ON Semiconductor, including built−in dynamic dark
current compensation to provide large signal to noise ratio (SNR) and
wide dynamic range (DR) over the entire operating temperature range.
The photopic optical filter provides a light response similar to that of
the human eye. Together the photopic light response and dark current
compensation insures accurate light level detection.
Features
• Senses Ambient Light and Provides an Output Current Proportional
to the Ambient Light Intensity
• Photopic Spectral Response
• Dynamic Dark Current Compensation
• Three Selectable Output Current Gain Modes in Approximately 10x
Steps
• Power Down Mode
• Less than 14 mA at 100 lux Active Power Consumption in Medium
Gain Mode (Less than 8 mA 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
Applications
• Saves display power in applications such as:
♦ Cell Phones, PDAs, MP3 players, GPS
♦ Cameras, Video Recorders
♦ Mobile Devices with Displays or Backlit Keypads
♦ Laptops, Notebooks, Digital Signage
♦ LCD TVs and Monitors, Digital Picture Frames
♦ Automobile Dashboard Displays and Infotainment
♦ LED Indoor/Outdoor Residential and Street Lights
