When the input is differential, the amplitude of the input is the
difference between the +IN and –IN input, or: (+IN) – (–IN).
The peak-to-peak amplitude of each input is
±1/2V
REF around
this common voltage. However, since the inputs are 180
°
out-of-phase, the peak-to-peak amplitude of the differential
voltage is +VREF to –VREF. The value of VREF also determines
the range of the voltage that may be common to both inputs,
as shown in Figure 4.

REF.
In each case, care should be taken to ensure that the output
impedance of the sources driving the +IN and –IN inputs are
matched. Often, a small capacitor (20pF) between the posi-
tive and negative input helps to match their impedance.
Otherwise, this may result in offset error, which will change
with both temperature and input voltage.
The input current on the analog inputs depends on a number
of factors as sample rate or input voltage. Essentially, the

explanation of the common voltage range for single-ended and differential inputs.
