LITEON LTR-329ALS-01

The LTR- 329ALS- 01 is a low voltage I²C digital light sensor [ALS] in a low cost miniature chiplled lead- free surface mount package. This sensor converts light intensity to a digital output signal capable of direct 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. There are altogether six gain settings (1X, 2X, 4X, 8X, 48X and 96X) available for user to configure. This CMOS design and factory- set one time trimming capability ensure minimal sensor- to- sensor variations for ease of manufacturability to the end customers.
