LITEON LTR-X1503

LTR-X1503 is an integrated low-voltage I²C ambient light sensor (ALS) and proximity sensor (PS) with a built-in emitter, housed in a single compact lead-free SMT package. The ALS delivers a linear response across a wide dynamic range, making it well-suited for applications in extremely low or high ambient light conditions. The integrated proximity sensor provides object detection at user-configurable distances. The PS features programmable interrupts with hysteresis, enabling event-driven operation without polling the sensor for data, thereby improving system efficiency. The CMOS design combined with factory one-time calibration ensures minimal unit-to-unit variation, simplifying manufacturing for end customers.
