The Maxim Integrated MAX44009 is the industry's lowest power ambient light sensor with analog to digital converter (ADC). The Maxim Integrated MAX44009 ambient light sensor features an operating current of less than 1µA and an ultra-wide 22-bit dynamic range of 0.045 lux to 188,000 lux.
Low-light operation allows easy operation in dark-glass applications. The on-chip photodiode's spectral response is optimized to mimic the human eye's perception of ambient light and incorporates IR and UV blocking capability. The adaptive gain block automatically selects the correct lux range to optimize the counts/lux. The Maxim Integrated MAX44009 ambient light sensor is designed to operate from a 1.7V to 3.6V supply voltage range and consumes only 0.65μA in full operation. The MAX44009 is designed for use in a variety of applications, including tablet PCs/notebook computers, TVs/projectors/displays, digital lighting management, portable devices, and more. The MAX44009EVKIT evaluation kit is a fully assembled and tested surface-mount PCB that evaluates the MAX44009.
