LTR-303ALS-01 Ambient Light Sensor Description The LTR-303ALS-01 is a low voltage I2C digital light sensor [ALS] in a low cost miniature chipled lead-free surface mount package. This sensor converts light intensity to a digital output signal capable of direct I2C 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. LTR-303ALS-01 Ambient Light Sensor Features I2C interface (Fast Mode @ 400kbit/s) Ultra small 6 pin ChipLED package 2.0mm(L), 2.0mm(B), 0.7mm(H) 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 - 70°C RoHS and Halogen free compliant Close to human eye spectral response Immunity to IR / UV Light Source Automatically rejects 50 / 60 Hz lightings flicker Full dynamic range from 0.01 lux to 64k lux 16-bit effective resolution LTR-303ALS-01 Ambient Light Sensor Applications Back-lighting Control in mobile/portable devices Touch Panel Control in mobile/portable devices LTR-303ALS-01 Ambient Light Sensor Ratings and Specifications Absolute Maximum Ratings at Ta = 25°C
