MAX44009：Industry's Lowest-Power Ambient Light Sensor with ADC

Reduces System Cost and Simplifies System Design

The MAX44009 ambient light sensor features an I²C digital output that is ideal for a number of portable applications such as smartphones, notebooks, and industrial sensors. At less than 1µA operating current, it is the lowest power ambient light sensor in the industry and features an ultra-wide 22-bit dynamic range from 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 IC is designed to operate from a 1.7V to 3.6V supply voltage range and consumes only 0.65µA in full operation. It is available in a small, 2mm x 2mm x 0.6mm UTDFN-Opto package.

Key Features Wide 0.045 Lux to 188,000 Lux Range Small, 2mm x 2mm x 0.6mm UTDFN-Opto VCC = 1.7V to 3.6V ICC = 0.65µA Operating Current -40°C to +85°C Temperature Range Device Address Options 1001 010x and 1001 011x
