A 600V RMS digital isolator ( MAX14850) and 3W transformer driver ( MAX256) provide the necessary isolated data and power connections to the host system. 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. 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. MAXSANTAFEEVSYS User Manual is available for download. 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. 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. 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. 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 MAX14851 has the same functionality and pin configurations,Īnd can be used as a footprint and functional The packages are specified over the -40☌ to +125☌ temperature range.įor improved performance, refer to the MAX14851. The MAX14850 is available in a narrow body,16-pin SOIC (10mm x 4mm) package (for which an evaluation kit is available) and 16-pin QSOP (3.9mm x 4.94mm) package. When used as a bus isolator, extra channels are available for power monitoring and reset signals. The MAX14850 can be used for isolating SPI busses, I 2C busses, RS-232, RS-485/RS-422 busses, and general-purpose isolation. Independent 3.0V to 5.5V supplies on each side of the isolator also make it suitable for use as a level translator. The two bidirectional channels are open drain and each is capable of data rates from DC to 2Mbps. 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 technology enables low power consumption and stable high-temperature performance.
