The MCP3204/3208 devices offer the choice of using the analog input channels configured as single-ended inputs or pseudo-differential pairs. When used in the pseudo-differential mode, each channel pair (i.e., CH0 and CH1, CH2 and CH3 etc.) is programmed to be the IN+ and IN- inputs as part of the command string transmitted to the device. The IN+ input can range from IN- to (VREF + IN-). The IN- input is limited to ?100 mV from the VSS rail. The IN- input can be used to cancel small signal common-mode noise which is present on both the IN+ and IN- inputs. When operating in the pseudo-differential mode, if the voltage level of IN+ is equal to or less than IN-, the resultant code will be 000h. If the voltage at IN+ is equal to or greater than {[VREF + (IN-)] - 1 LSB}, then the output code will be FFFh. If the voltage level at IN- is more than 1 LSB below VSS, the voltage level at the IN+ input will have to go below VSS to see the 000h output code. Conversely, if IN- is more than 1 LSB above VSS, then the FFFh code will not be seen unless the IN+ input level goes above VREF level.

    • values

      public static McpAdc.Type[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static McpAdc.Type valueOf​(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null
