Introduction: …and;
.2. Proximity Presence: ( ASR-8800, 8-Pin OCDFN package )
Detect object presence by means of the Infra-Red reflection light
intensity.
Amic Technology Corporation
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
