LTR-778ALS-BE - Optical Sensor

Datasheet Summary

Description

The LTR-778ALS-BE 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 signal capable of direct I2C interface.

Features

2-level fault detection that allows further protection against un-intended VCSEL current trigger or surge caused by short circuit. 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 t.
