MAX44009 Ambient Light Sensor - I2C

Ambient Light Sensor

Overview

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.

An outstanding spiritual treasure trove
Format: Paperback
This book is a treasure of spiritual insights and guidelines to live a devout life. Although written hundreds of years ago, it is remarkably apt and relevant today. St. Francis de Sales was a spiritual director, and it is clear why he was so sought after and valued. This book is one I turn to again and again as life circumstances change, and I have given away copies to several fellow pilgrims. This spiritual classic receives my highest endorsement.

challenging and inspiring
Format: Kindle
I trudged my way through sections of this that seemed overly legalistic, but all in all, another inspiring text from saints whose sole desire was to be united with God, to find their all in Christ, and to become more and more like him through his suffering, death, and resurrection.
