2 Analog Interface

The analog input to the EVM is routed from a three-wire screw terminal screw at J3.1, which provides access to the INP terminal, referenced to J3.3, GND1. J3.2 provides access to either the INN terminal for the AMC1400 or the SHTDN terminal for the AMC1411. By default, J3.2 is shorted to GND1 by a 0-Ω resistor, R5.
