+ | ==== Input Interface ==== | ||
+ | The circuit consists of an input current-to-voltage converter, a level shifting circuit, an ADC stage, and an output isolation stage. The system can process 4 to 20 mA input signals by connecting the positive terminal to Pin 1 and the ground terminal to Pin 2 of J2 terminal block. A diode is connected to provide protection against an accidental reverse connection of the input current source. The calculation of gain and resistor values can be found in [[ADI>/ | ||

When using the EVAL-CN0336-PMDZ PMOD board, the 3.3V power for the PMOD comes directly from the host board it is connected to. The power from the host is generally capable of providing up to 100 mA at 3.3V, but for complete PMOD power specifications can be found at [[https:// | When using the EVAL-CN0336-PMDZ PMOD board, the 3.3V power for the PMOD comes directly from the host board it is connected to.
