MAX9635
Industry's Lowest-Power Ambient Light Sensor with ADC
Low-Power Ambient Light Sensor Reduces System Cost and Simplifies System Design
Part Details
- Wide 0.045 Lux to 188,000 Lux Range
- Small, 2mm x 2mm x 0.6mm OTDFN
- VCC = 1.7V to 3.6V
- ICC = 0.65µA Operating Current
- -40°C to +85°C Temperature Range
The MAX9635 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 supply voltage range of 1.7V to 3.6V and consumes only 0.65µA in full operation. It is available in a small, 2mm x 2mm x 0.6mm OTDFN package.
