Analog Interface
The ADS8402/ADS8412EVM analog-to-digital converter has a unipolar
differential input. A unipolar differential input is a differential signal (inverting
and noninverting input is 180 degrees out of phase) that is level shifted such
that the signals levels are always equal to or above zero volts. The
peak-to-peak amplitude on each input pin can be as large as the reference
voltage. See the respective product data sheet for more information.
