public static enum McpAdc.Type extends java.lang.Enum<McpAdc.Type>
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.
