Product Details

The MAX11205PMB1 peripheral module provides the necessary hardware to interface the MAX11205 16-bit ADC to any system that utilizes Pmod™-compatible expansion ports configurable for GPIO interface. The IC is an ultra-low-power (< 300µA max active current), high-resolution, serial-output ADC. This device provides the highest resolution per unit power in the industry and is optimized for applications that require very high dynamic range with low power, such as sensors on a 4mA to 20mA industrial control loop. The voltage reference for the IC is supplied by a MAX6037 (2.5V) that is also on the module. The filtered power-supply voltage from the host can be optionally passed (jumper selectable) through a MAX8510 ultra-low-noise LDO, allowing empirical evaluation of performance with different power sources.
Refer to the MAX11205 IC data sheet for detailed information regarding operation of the IC.

Features and Benefits

  • Data Converter, Interface, Clock, Sensor, and Other Modules Included to Address Many Design Needs
  • Plug in Modules Enable Rapid Hardware Prototyping
  • Proven Software Drivers Reduce Development Time
  • FPGA Configuration Files Included to Simplify Design Effort

Product Details

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.
