I am planning on using multiple inputs in differential mode with an AD7194.
Both inputs of one differential pair will be at 0 to +5 millivolts. This pair will be using unbuffered mode as the spec sheet suggests.
Both inputs of another differential pair will be at about 2.5 volts. This pair will be using buffered mode.
My questions are this:
Are the programmable gains of 1..128 available in unbuffered mode?
Can I expect to see any degradation of the measured value on the pair at 2.5 volts do to the pair near 0 volts?
