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 1 current compensation to provide large signal to noise ratio (SNR) and
