ABRIDGED 19-5284; Rev 0; 8/10 TION KIT EVALUA BLE IL AVA A Industry’s Lowest-Power Ambient Light Sensor with ADC Features The MAX9635 ambient light sensor features an I2C digi- S Wide 0.045 Lux to 188,000 Lux Range tal 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. S Small, 2mm x 2mm x 0.6mm UTDFN-Opto S VCC = 1.7V to 3.6V S ICC = 0.65µA Operating Current S -40NC to +85NC Temperature Range 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.
