11.2.1 Input stage
11.2 Analog inputs
When the device enters SPI control mode, the output data standard and data format are
determined by the level on pin SDIO at the instant a transition is triggered by a falling
edge on CS.
The active ADC1210S operating mode (Power-up, Power-down or Sleep) can be selected
via the SPI interface (see
described in
Table 10.
Selecting the output data standard
The output data standard (CMOS or LVDS DDR) can be selected via the SPI interface
(see
HIGH, otherwise CMOS is selected.
Selecting the output data format
The output data format can be selected via the SPI interface (offset binary, two’s
complement or gray code; see
binary or two’s complement). Offset binary is selected when DFS is LOW. When DFS is
HIGH, two’s complement is selected.
The analog input of the ADC1210S supports differential or single-ended input drive.
Optimal performance is achieved using differential inputs with the common-mode input
voltage (V
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

Discharge (ESD) protection and circuit and package parasitics, is shown in
