NOA1305

Ambient Light Sensor with

Current Compensation

Description

The NOA1305 ambient light sensor (ALS) is designed for handheld

interface, internal clock oscillator and a power down mode. The built

in dynamic dark current compensation and precision calibration

capability coupled with excellent IR and 50/60 Hz flicker rejection

enables highly accurate measurements from very low light levels to

full sunlight. The device can support simple count equals lux readings

in interrupt−driven or polling modes. The NOA1305 employs proprietary

CMOS image sensing technology from ON Semiconductor to provide

large signal to noise ratio (SNR) and wide dynamic range (DR) over

the entire operating temperature range. The optical filter used with this

chip provides a light response similar to that of the human eye.
