Product Details

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.
