The MAX5216PMB1 peripheral module provides the necessary hardware to interface the MAX5216 16-bit DAC to any system that utilizes Pmod™-compatible expansion ports configurable for SPI communication. The IC is a single-channel, low-power, buffered voltage-output DAC. The reference voltage for the DAC is provided by a 2.5V output version of the MAX6029 voltage reference (0.15% initial accuracy, 30ppm/°C). Digital noise is minimized by having SPI input buffers powered down after completion of each serial input frame.

Refer to the MAX5216 IC data sheet for detailed information regarding operation of the IC.

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.
