LTR-553ALS-WA

深圳市政鸿微电子有限公司优势供应光宝：LTR-553ALS-WA

Description

The LTR-553ALS-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 signal 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 and detector), LTR-553ALS-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 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.
