Introduction: Amic Technology sensors are detecting;

.1. Ambient light detection: ( ASR-8600, 6-Pin OCDFN package )

Detect light intensity (lux)

Detect light spectrum, including human visible light and near Infrared

………….and


Introduction: …and;

.2. Proximity Presence: ( ASR-8800, 8-Pin OCDFN package )

Detect object presence by means of the Infra-Red reflection light

intensity.

ASR8800

(4.2mmx3.2mmx1.1mm)


ASR8810

(3.94mmx2.36mmx0.65mm)


Key Features:

•High functionality integration in a single chip offering low cost

and easy system migration.

•Wide light spectrum range coverage

•Very low power consumption

•I2C interface with interrupt pin for easy control

•Exceptional dynamic range of 16-bits and up to 400K lux

detection.

•Crosstalk cancellation done by a single command set

•Integrated 8-bit ADC for Solar UV Index, see table


Key features,

Amic’s proximity sensor advantage in Smart Phone application

•Different aperture pitch supported ( 2.4mm , 1.4mm , 1.0mm )

•Strong/Smart capability of crosstalk cancellation

•Separate 8-bits ADC for Proximity count sensing, Infra-red

VSEL (850nm) for ultra low crosstalk noise.

•No extra isolator needed (reducing mechanical overhead and

costs)

•Low Power consumption

•No blind zone issue


Key features, Integrated crosstalk cancellation.

No need for mechanical isolator solutions
