ASR8601
Preliminary
Ambient Light Sensor with I2C digital interface
Wide Lux Detecting Range and Full IR Rejection
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
„ Industrial sensor
