Product Details

The MAX22005PMB# (peripheral module board) provides a Pmod™-compatible hardware solution to evaluate the MAX22005 Twelve-Channel Configurable Industrial Analog Input. Refer to the MAX22005 IC data sheet for more details on the operation of the IC and its register map.

The MAX22005PMB# is most easily evaluated by configuring four universal analog inputs with the Munich GUI software through the USB2PMB2# adapter board. Alternatively, any SPI-compatible microcontroller, adapter board, or FPGA can be used along with a custom driver to evaluate the board.

The PCB dimension is just 99mm long x 23mm wide, with the width determined by the size of the terminal block.

Note the module provides a subset of the MAX22005 features. For greater flexibility, refer to the MAX22005 Evaluation Kit.

Product Details

The MAX22005 evaluation kit (EV kit) provides a proven design to evaluate the MAX22005, 12-Channel factory-calibrated configurable industrial-analog input. The MAX22005 EV kit includes the MAX22005 evaluation board and a graphical user interface (GUI) that provides communication from a PC to the target device through a USB port.

The GUI is compatible with Windows^® 10 for exercising the features of the MAX22005 IC. The EV kit GUI allows the user to read the 24-bit ADC conversion result for any of the input channels through the high-speed SPI interface in single-ended, differential, or multifunctional configurations. The SPI interface is galvanically isolated from the USB port.

The MAX22005 EV kit must be powered from an external +24V power supply through the power jack (J100). The on-board DC-DC converters provide ±15V HVDD/HVSS and +3.3V AVDD/DVDD power rails for the entire board.

The MAX22005 EV kit board comes with a MAX22005ALM+ installed in a 48-pin, 7.5mm x 7.0mm LGA package.
