NOA1211
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 m A at dark and its quiescent current consumption is less than 200 p A in power down mode. The device can operate over a very wide range of voltages from 2 V to 5.5 V. The NOA1211 employs proprietary CMOS image sensing technology from ON Semiconductor, including built- in dynamic dark current pensation 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 pensation insures accurate light level detection.
