Introduction

The LTR- 507ALS- WA is an integrated I2C digital light sensor [ALS] and proximity sensor [PS] with built- in LED driver, in a miniature chipled lead- free surface mount package. This device converts light intensity to a digital output signal capable of direct I2C interface. It provides a linear response over a wide dynamic range and is well suited to applications under high ambient brightness. With built- in proximity sensor, LTR- 507ALS- WA offers the feature to detect object at a user configurable distance of typical 50cm Gray Card. The device supports an interrupt feature that removes the need to poll the sensor for a reading which improves system efficiency. The device also supports several features that help to minimize the occurrence of false triggering. This CMOS design and factory- set one time trimming capability ensure minimal device- to- device variations for ease of manufacturability to the end customers.
