2.3.1 ADC Input SMA Connections

Each ADC channel is connected to two SMA input connectors. 0402 footprints are provided to add a first-order, low-pass filter network on all ADC channels. By default, the filter capacitors are uninstalled and the filter resistors are populated with 0 ohms. Use NP0/C0G type capacitors and low-tolerance resistors to maintain AC performance when choosing to populate these footprints with a low-pass filter circuit.

Additionally, the ADC negative input connectors (for example, AIN1M) have the option to be shorted to GND with a jumper to allow for single-ended input signals. Figure 2-2 shows the input connections for a digital interface.
