See Ordering Information for details. Description Data Sheet The MAX44000 combines a wide-dynamic range ambient light sensor with an integrated infrared proximity sensor. This sensor IC is an ideal solution for touch-screen portable devices. Click here to be notified when full data sheet is available. Its ambient sensor has the ability to make wide dynamic range (0.03 lux to 65,535 lux) measurements. The on-chip IR proximity detector is matched with an integrated IR LED transmitter to improve noise immunity. All readings are available through an I2C communication bus. A programmable interrupt pin minimizes the need to poll the device for data, freeing up microcontroller resources, reducing system software overhead and, ultimately, reducing power consumption. The IC is designed to drive an external IR LED and can operate from a VDD of 1.7V to 3.6V. It consumes just 5A operating current when only the ambient light sensor is enabled, and 7A when the proximity receiver and driver are enabled. In ambient plus proximity mode, it consumes as low as 11A, including external IR LED current.
