2.5.5
Channel 1 is a differential input with two possible circuit selections for each
single-ended input (circuit A and circuit B). Using the MCP3905/6 Evaluation Board,
either of the inputs can be connected to the RC or to A
differential experiments. JPX should be shorted to ground for all single-ended input
configurations.

Circuit B includes 4 resistor sockets and a mechanical potentiometer. This allows for
experiments calibrating the output of the MCP3905 by changing Channel 1’s input
signal amplitude.
