Input stage description
The analog input of the ADC1413S supports a differential or a single-ended input drive.
Optimal performance is achieved using differential inputs with the common-mode input
voltage (V
I(cm)
) on pins INP and INM set to 0.5V
DDA
.
The full-scale analog input voltage range is configurable between 1 V (p-p) and 2 V (p-p)
via a programmable internal reference (see
Section 11.2
and
Table 21
).
Figure 6
shows the equivalent circuit of the sample-and-hold input stage, including
ElectroStatic Discharge (ESD) protection and circuit and package parasitics.
The sample phase occurs when the internal clock (derived from the clock signal on pin
CLKP/CLKM) is HIGH. The voltage is then held on the sampling capacitors. When the
clock signal goes LOW, the stage enters the hold phase and the voltage information is
transmitted to the ADC core.
