UVIS25

UVIS25 Digital UV Index sensor: 0 - 15 UV Index output range Datasheet - preliminary data LGA-10L (2.5 x 2.5 x 0.76 mm) Features 0 - 15 UV Index output range Resolution: UVI/16 Active and power down modes Continuous reading at 1 Hz ODR / one shot mode Interrupt functions: Data Ready and UVI thresholds SPI and I²C interfaces Supply voltage: 1.7 to 3.6 V ECOPACK® lead-free compliant Description The UVIS25 is a digital UV Index sensor able to provide an accurate measurement of the Ultraviolet radiation index (UVI) from the sunlight. It includes a sensing element and a mixed signal ASIC to provide the UV Index data trough I2C and SPI interfaces. A dedicated technology has been developed to achieve the best accuracy for UV Index measurements. The UVIS25 allows the measurement of the UV Index, without the need of a dedicated algorithm to calculate the UV Index and without specific calibrations at customer manufacturing line. The device can be configured to generate interrupt events based on a threshold crossing or when a new set of data is generated. The event is available in a register as well as in a dedicated pin. The UVIS25 is available in a full-mold LGA package (LGA). It is guaranteed to operate over a temperature range extending from -20°C to +85°C. The package is transparent to allow external solar radiation to reach the sensing element.
