LTR-553ALS-01 Description

Short technical summary and product information.

The LTR-553ALS-01 from Lite-On Inc. is a versatile optical sensor combining a digital ambient light sensor (ALS) and a proximity sensor (PS) in a single miniature chipLED surface mount package. This device utilizes an I2C interface, supporting Fast Mode at 400kbit/s, for direct digital output.

 

Key features include a wide dynamic range for light detection from 0.01 lux to 64k lux with 16-bit resolution, and a proximity sensor with 11-bit resolution. It operates within a supply voltage range of 2.4V to 3.6V and has a temperature range of -30°C to +70°C. The sensor includes built-in temperature compensation and supports a standby mode for low power consumption.

 

Designed for applications requiring light sensing and object detection, the LTR-553ALS-01 is suitable for controlling display backlights in mobile devices, computing, and consumer electronics. Its proximity sensing capability allows for user-configurable detection distances, and an interrupt feature enhances system efficiency by eliminating the need for constant polling. The sensor is RoHS and Halogen free compliant.
