1 / 41 page  Digital UVA / UVB Energy Sensor ZOPT2202 Datasheet © 2016 Integrated Device Technology, Inc 1 September 21, 2016 Description The ZOPT2202 Sensor integrates two types of ultra-violet optical sensors: one that is primarily sensitive in the UVA spectral range and one that is sensitive in the UVB spectral range. The device is connected via an I²C interface to a microcontroller. Other I²C or SMBus devices can be connected to the same inter- face. The device has a programmable interrupt with hysteresis to respond to events and reduce the microcontroller tasks. A major application of the device is in smart phones or other mobile devices to enable UVA and UVB energy level measure- ments in support of diverse health care applications or contextual awareness algorithms. Features Very high sensitivity for UVA and UVB energy levels Superior visible light and infrared energy suppression Very stable spectral response over angle of light incidence Large dynamic range Excellent temperature compensation Lowest conversion repeat noise Parallel operation of UVA and UVB sensor I²C interface capable of standard mode (100kHz) or fast mode (400kHz) communication; 1.8V logic compatible Programmable interrupt function for UVA or UVB sensor with upper and lower thresholds Sensor Features UVA/UVB sensor in a matrix array arrangement Configurable output resolution: 13 to 20 bits Configurable analog gain: 1 to 18 Linear output code Fluorescent light flicker immunity Physical Characteristics Wide operation temperature: - 40°C to +90°C Wide supply voltage: 1.7V to 3.6V Minimum active current at maximum duty cycle: — Single channel: 110µA typical — Dual channel: 130µA typical Note: Average current is proportionally lower with lower measurement rates. Low standby current: 1µA typical Packages: — LGA6 (2.0 2.2 0.7 mm) — TSV (1.1 1.2 0.26 mm) ZOPT2202 Application Circuit VDD GND INT SDA SCL SDA SCL VDD GND INT µC ZOPT2202 VDD1 VDD2 VDD2 VDD1: 1.7 to 3.6 V VDD2: 1.7 to 3.6 V |
