2 Analog Interface

As an analog interface, the evaluation board uses fully differential amplifiers (FDAs) to drive the ADS9218 input signals. The ADS9218 includes an integrated voltage reference, but an external reference can be used and is jumper selectable on the hardware. This section covers driver details, including jumper configuration for different input signal options.
