LTR-311ALS-02 Datasheet | LITEON

Description The LTR-311ALS-02 is an integrated low voltage I2C ambient light sensor (ALS) in a single 2.40 x 2.0mm miniature Chip LED lead-free surface mount package. The ALS provides a linear response over a wide dynamic range, which is well suited to applications under very low or bright ambient brightness. The sensor CMOS design and factory-set one-time trimming capability ensure minimal sensor-to-sensor variations for ease of manufacturability to the end customers. Application - Control brightness of display panel in mobile, puting, and consumer devices.
