MAX14850PMB1

$23.76

Description/Applications

The MAX14850PMB1 peripheral module utilizes the MAX14850 digital isolator to isolate another SPI- or UART-based module from any host system that utilizes Pmod™-compatible expansion ports configurable for either a UART or SPI interface. This peripheral module is first plugged into the host Pmod port. Another UART- or SPI-based module plugged into the 12-pin Pmod-compatible connector on this peripheral module is galvanically isolated from the host and referenced to a secondary power supply connected to this peripheral module.

The IC is a 6-channel digital isolator utilizing Maxim's proprietary process technology, whose monolithic design provides a compact and low-cost transfer of digital signals between circuits with different power domains. Of the six total channels, the four unidirectional channels are each capable of DC to 50Mbps, with two of the four channels passing data across the isolation barrier in each direction. The two bidirectional channels are open drain and each is capable of data rates from DC to 2Mbps.

Refer to the MAX14850 IC data sheet for detailed information regarding operation of the IC.

Features

Isolates SPI- or UART-Based Pmod-Compatible Modules from the Host System
Data Rates from 2Mbps to 20Mbps or Greater, Depending on Configuration
2-Pin Header to Connect External Voltage for Isolated Module
600V_RMS Isolation for 60s
Isolates Four SPI or UART Signals and Two Control Signals
Short-Circuit Protection on Unidirectional Outputs
12-Pin Pmod-Compatible Male Connector to Host
12-Pin Pmod-Compatible Female Connection for Module to be Isolated
RoHS Compliant
Proven PCB Layout
Fully Assembled and Tested

Evaluation Board

MAXPMBAE

Description/Applications

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.

Features

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

MAXSANTAFEEVSYS

Description/Applications

The MAXSANTAFEEVSYS kit allows users to quickly demonstrate and evaluate the functionality of the MAXREFDES5 4-channel 16-bit, isolated analog front end (AFE) reference design without the need for a bench power supply, signal generator equipment, or Xilinx development kit. The reference design board connects to a PC through an included USB-to-SPI adapter that provides both power and data communication to the board. To test the AFE reference design, a USB-powered signal generator board utilizing one of Maxim’s digital-to-analog converters (DAC) is also included. A Windows^®-based graphical user interface (GUI) communicates with the boards for generating various analog signal test patterns and simplified access to AFE measurement data.

MAXSANTAFEEVSYS User Manual is available for download.

The MAXREFDES5 reference design is a 4-channel analog front end (AFE) that accepts -10V to +10V, 0V to 10V, and 4–20mA current loop signals. The design integrates a 16-bit ADC with multirange input programmability (MAX1301) plus low-noise, high-impedance analog buffers (MAX9632) on two of the input channels and an ultra-high precision 4.096V voltage reference (MAX6126) to achieve maximum performance from the 16-bit system. A 600V_RMS digital isolator (MAX14850) and 3W transformer driver (MAX256) provide the necessary isolated data and power connections to the host system. LDO regulators (MAX1659) provide regulated +12V, -12V, and 5V power rails to the analog front end.
