The LTR-507ALS-WA is an integrated I2C digital light sensor (ALS) and proximity sensor (PS) with a built-in LED driver, presented in a miniature chipled lead-free surface mount package. This device offers a linear response over a wide dynamic range, making it suitable for applications with high ambient brightness. It features a configurable proximity detection distance of up to 50cm and supports an interrupt function to enhance system efficiency by eliminating the need for constant polling. The CMOS design and factory-set trimming minimize device-to-device variations, simplifying manufacturing.
