LITEON LTR-390UV-01

The LTR- 390UV- 01 is an integrated low voltage I²C ambient light sensor (ALS) and ultraviolet light sensor (UVs) in a single miniature 2×2mm chipled lead- free surface mount package. This sensor converts light intensity to a digital output signal capable of direct I²C interface. It provides a linear ALS response over a wide dynamic range from 0.01 lux to 157k lux and is well suited to applications under high ambient brightness. The sensor has a programmable interrupt with hysteresis to response to events and that removes the need to poll the sensor for a reading which improves system efficiency. This CMOS design and factory- set one time trimming capability ensure minimal sensor- to- sensor variations for ease of manufacturability to the end customers.
