MAX44004 Digital Ambient Light Sensor The MAX44004 is a wide dynamic range, lowpower ambient light sensor ALS ideal for many light sensing applications tablets, displays, accessories, medical devices, and light management systems. The on-chip ambient sensor has the power to measure the exact visible light from lux to 65,000 lux and communicate through an I2C digital communication bus. The IC has patented sensors, filters, and circuitry to mimic the human eye response. With on-chip calibration registers, it performs the same in different light conditions i.e., fluorescent, incandescent . The interrupt pin minimizes the need of constant polling of the device, freeing up microcontroller resources for efficient communication and thus reducing overall power consumption. The part-to-part matching is optimized by proprietary Maxim process to speed up end-product development time. The IC can operate from a VDD of 1.7V to 3.6V, including both supply and I2C times. It consumes just 5µA operating current.
