EVALUATION KIT AVAILABLE MAX44009 Industrys Lowest-Power Ambient Light Sensor with ADC General Description Features 2 The MAX44009 ambient light sensor features an I C S Wide 0.045 Lux to 188,000 Lux Range digital output that is ideal for a number of portable appli- S Small, 2mm x 2mm x 0.6mm UTDFN-Opto cations such as smartphones, notebooks, and industrial S V = 1.7V to 3.6V CC sensors. At less than 1A operating current, it is the S I = 0.65A Operating Current lowest power ambient light sensor in the industry and CC features an ultra-wide 22-bit dynamic range from 0.045 S -40N C to +85NC Temperature Range lux to 188,000 lux. S Device Address Options Low-light operation allows easy operation in dark-glass 1001 010x and 1001 011x applications. The on-chip photodiodes spectral response is optimized to mimic the human eyes 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 sup- ply voltage range and consumes only 0.65A in full operation. It is available in a small, 2mm x 2mm x 0.6mm UTDFN-Opto package.
