General Description
The MAX5216PMB1 peripheral module provides the nec-
essary hardware to interface the MAX5216 16-bit DAC to
any system that utilizes PmodK-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 informa-
tion regarding operation of the IC.

MAX5216PMB1 Peripheral Module
Detailed Description
SPI Interface
The MAX5216PMB1 peripheral module can plug directly
into a Pmod-compatible port (configured for SPI) through
connector J1. For information on the SPI protocol, refer to
the MAX5214/MAX5216 IC data sheet.
J1 provides connection of the module to the Pmod host.
See Table 1.
Connector J2 provides connection to the IC pins.
Jumper JP1 allows the user to select between reference
voltages for the DAC IC (see Table 3).
Reference Voltage
The MAX5216PMB1 peripheral module contains a
MAX6029 precision voltage reference for the REF input
of the IC. The MAX6029 outputs a 2.5V reference.
Software and FPGA code
Example software and drivers are available that execute
directly without modification on several FPGA devel-
opment boards that support an integrated or synthe-
sized microprocessor. These boards include the Digilent
Component List

Nexys 3, Avnet LX9, and Avnet ZEDBoard, although
other platforms can be added over time. Maxim provides
complete Xilinx ISE projects containing HDL, Platform
Studio, and SDK projects. In addition, a synthesized bit
stream, ready for FPGA download, is provided for the
demonstration application.
The software project (for the SDK) contains several source
files intended to accelerate customer evaluation and design.
These include a base application (maximModules.c) that
demonstrates module functionality and uses an API inter-
face (maximDeviceSpecificUtilities.c) to set and access
Maxim device functions within a specific module.
The source code is written in standard ANSI C format, and
all API documentation including theory/operation, register
description, and function prototypes are documented in
the API interface file (maximDeviceSpecificUtilities.h & .c).
The complete software kit is available for download
www.maxim-ic.com. Quick start instructions are also
available as a separate document.
