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
