General Description

The ASR8601 is an ambient light (ALS) sensor with wide lux

detecting range and full IR rejection. It features an I2C digital

output and provides innovative algorithms which can be

friendly in application.

ASR8601 ALS sensing offers ASC (Auto Scale Control)

mode other than traditional manual mode. With ASC mode,

ASR8601 can automatically adjust the sensing time and gain

value to the best resolution according to the various light

intensity. User just simply needs to read the measured light

data in accuracy without any other setting. The ASC output

data is in dynamic range of 16 bits with 12 bits resolution.

And under high intensity mode sensing (AI_H mode), the

sensing intensity range can be up to 120K lux.

Applications

Surveillance camera

Notebook / Monitor

Smart phone (touch screen disable and backlight control)

LCD display (backlight control)

Table PC

PDA
