Description 2 The LTR-559ALS-01 is an integrated low voltage I C digital light sensor ALS and proximity sensor PS with built-in emitter, in a single miniature chipled lead-free surface mount package. This sensor converts light intensity to a digital output signal 2 capable of direct I C interface. It provides a linear response over a wide dynamic range from 0.01 lux to 64k lux and is well suited to applications under high ambient brightness. With built-in proximity sensor (emitter and detector), LTR-559ALS-01 offers the feature to detect object at a user configurable distance. The sensor supports an interrupt feature that removes the need to poll the sensor for a reading which improves system efficiency. The sensor 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 sensor-to-sensor variations for ease of manufacturability to the end customers. 2.
