MAX4824

• 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

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.

The MAX4824PMB1 peripheral module provides the necessary hardware to interface the MAX4824 8-channel relay driver to any system that utilizes Pmod™-compatible expansion ports configurable for GPIO communication. Each independent channel in the IC features a 2.7Ω (typ) on-resistance and is guaranteed to sink 70mA (min) of load current. A zener kickback-protection circuit significantly reduces recovery time in applications where switching speed is critical. When driving relays, a unique power-save mode allows relay current to be reduced to a level just above the relay hold-current threshold. This mode keeps the relay activated while significantly reducing the power consumption.
