There is "Input coupling" setting in Page 27 of the datasheet, which input setting is this setting?
How will the input behavior change with AC coupling setting and DC coupling setting?
I read the datasheet.
The datasheet is "For more information about this feature and others, see the AN - 877 Application Note, Interfacing to High Speed ADCs via SPI at www.analog.com."
I read the application notes.
The application note is called "Analog In (0x02C) see the device data sheet for details".
