Part No.: LTR-501ALS-01 DATA SHEET
1. Description
The LTR-501ALS-01 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 I 2
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, LTR-501ALS-01 offers the feature to detect object at a user configurable distance up to 10cm.
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.
