LITEON LTR-308ALS-01

The LTR- 308ALS- 01 is an integrated low voltage I2C ambient light sensor (ALS) in a single 2x2mm miniature chipled lead- free surface mount package. The ALS provides a linear response over a wide dynamic range, which is well suited to applications under very low or bright 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. Very low power consumption with sleep mode capability Operating voltage ranges: 1.7V to 3.6V Operating temperature ranges: - 40 to +85°C Built- in temperature compensation circuit Programmable interrupt function for ALS with upper and lower thresholds RoHS and Halogen free compliant
