Description The LTR-329ALS-01 is a low voltage I2C digital light sensor ALS in a low cost miniature chipled lead-free surface mount package. 2 This sensor converts light intensity to a digital output signal capable of direct I C 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. 2. Features I2C interface (Fast Mode 400kbit/s) Ultra-small ChipLED package Built-in temperature compensation circuit Low active power consumption with standby mode Supply voltage range from 2.4V to 3.6V capable of 1.7V logic voltage Operating temperature range from -30 C to +70 C RoHS and Halogen free compliant Light Sensor Close to human eye spectral response Immunity to IR / UV Light Source Automatically rejects 50 / 60 Hz lightings flicker 6 dynamic range from 0.01 lux to 64k lux 16-bit effective resolution 3.
