PRODUCTION DATA.
Figure 83 shows an example of the digital connections between the host µC and ADC. Not all I/O connections are necessary for basic ADC operation; see the Unused Inputs and Outputs section. Impedance-matching resistors in series with the I/O PCB traces help reduce overshoot and ringing, and are particularly helpful over long trace runs.
