LTR-558ALS-WA

1. Description

  The LTR-558ALS-WA is an integrated low voltage I2C 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 ** capable of direct I2C 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 anddetector), LTR-558ALS-WA 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 readingwhich 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.
