Brief Description
The ZOPT2201 Sensor integrates an ambient light sensor (ALS) and ultraviolet energy sensor (UVBS). The device can be connected via an I²C interface to an external microcontroller. Other I²C or SMBus devices can be connected to the same interface. The device has a programmable interrupt with hysteresis to respond to events and reduce the microcontroller tasks.

FEATUREs
◾ High ambient light and UVB energy sensitivity
◾ Superior infrared energy suppression
◾ Very stable spectral response over angle of light incidence
◾ Wide dynamic range
◾ Excellent temperature compensation
◾ Lowest conversion repeat noise
◾ I²C interface capable of standard mode (100kHz) or fast mode
   (400kHz) communication; 1.8V logic compatible
◾ Programmable interrupt function for ALS and UVBS with
   upper and lower thresholds

ALS Features
◾ Integrated ALS closely matches human eye response for high
   lux accuracy over different light sources
◾ Absolute sensitivity: 0.008 lux to 157000 lux
◾ Configurable output resolution: 13 to 20 bits
◾ Configurable analog gain: x1 to x18
◾ Linear output code
◾ 50Hz/60Hz light flicker immunity
◾ Fluorescent light flicker immunity

UVBS Features
◾ Linear UV index measurement (1 to >11)
◾ Tailored temperature compensation

APPLICATIONs
◾ Cellular phones
◾ Notebooks
◾ Consumer devices
