Industry's Lowest-Power Ambient Light Sensor with ADC

Reduces System Cost and Simplifies System Design

Product Details

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. It is available in a small, 2mm x 2mm x 0.6mm UTDFN-Opto package.

Description

The MAX44009 evaluation kit (EV kit) is a fully assembled and tested surface-mount PCB that evaluates the MAX44009 low-power ambient light sensor. The EV kit can be powered directly from the universal serial bus (USB) or from a single-supply voltage of 1.7V to 3.6V.

The EV kit provides an on-board I²C/SMBus interface and is connected to the computer through the USB port. The EV kit includes Windows XP®-, Windows Vista®-, and Windows® 7-compatible software that provides a simple user interface for exercising the device's features. The program is menu driven and offers a graphical user interface (GUI) complete with control buttons and status displays.

The on-board device can also be controlled by an external master, allowing users to test different code implementations to interface with the part.

Description

Maxim Analog Essentials is a collection of peripheral modules which can plug directly into any FPGA/CPU expansion port which follows the Pmod™ standard established by Digilent, Inc. The collection includes modules containing a wide variety of commonly used analog and mixed signal functions. The modules are supported by software which includes FPGA configuration files for three popular FPGA platforms: Avnet LX-9, Digilent Nexys 3 and Avnet ZEDBoard, as well as example programs to exercise and demonstrate each module. While the example programs demonstrate the module’s functionality, they are well partitioned and documented allowing the core routines to be easily cut and pasted into your own programs. The combination of plug-in simplicity and easy software integration allows for quick migration from idea to working prototype.
