5.1.1 Voltage Measurement

Two methods are available for voltage measurement: single-

ended and differential measurement.

With the single-ended type the voltage to be measured is con-

nected between an analogue input (In+) and analogue ground

(AGND). Differential measurements are realized by using two

analogue inputs (In+ and In-). Measuring range is between 0

and ±10 V.

Note: With differential measurements both voltages have to be

within 10 V referred to AGND (Common-Mode-Range).

It is recommended to connect the In- to A

GND

with a high ohmic

resistance.
