Signal connections

Analog input

You can configure the analog inputs for SE or DIFF mode. The input voltage range is software selectable for
±10 V, ±5 V, ±2 V, or ±1 V.
With SE mode, connect up to eight inputs to

Connect one wire to the signal you want to measure (

Connect one wire to the analog ground reference (
With DIFF mode, connect up to four differential inputs to
two wires plus a ground reference:

Connect one wire to the high/positive signal (

Connect one wire to the low/negative signal (

Connect one wire to the analog ground reference (
Floating voltage source
When connecting DIFF voltage inputs to a floating voltage source, make sure the DIFF input channel has a DC
return path to ground. To create this path, connect a resistor from each low channel input to an AGND pin. A
value of approximately 100 kΩ can be used for most applications.
