NOA1212
Ambient Light Sensor with
Dark Current Compensation
Description The NOA1212 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 NOA1212 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. www.onsemi.com 1 CUDFN6
