Figure 6 : Input dynamic range for the various configurations
The applications requiring single-ended inputs
can be configured like reported on Figure 7 for an
AC-coupled input or on Figure 8 and 9 for a
DC-coupled input.
In the case of AC-coupled analog input, the
analog inputs VIN and VINB are biased to the
same voltage that is the common mode voltage of
the circuit (INCM). The INCM and reference
voltages may remain at their internal level but can
also be fixed externally.
Figure 7 : AC-coupled Single-ended input
In the case of DC-coupled analog input with 1V
DC signal, the DC component of the analog input
set the common mode voltage. As an example
figure 8, INCM is set to the 1V DC analog input
while VREFM is connected to ground and VREFP
let internal; we achieve a 2Vpp differential
amplitude.
Figure 8 : DC-coupled 2Vpp analog input
Figure 9 describes a configuration for a 1Vpp ana-
log signal with a 0.5V DC input. In this case, while
VREFP is kept internal at 1V, VREFM is connect-
ed to VINB and INCM, externally to 0.5V; the dy-
namic is then 1Vpp (VREFP-VREFM=0.5V).
