Integrated Low Voltage I2C Ambient Light Sensor - LTR-308ALS-01

Product Specification

LTR-308ALS-01 Ambient Light Sensor Description
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.
