3.1.1.4 External Reference

The ADS1263 can accept an external reference in addition to the internal and supply reference options. The external reference inputs are shared with pins AIN0 through AIN5. ADC1 and ADC2 can share a reference source, though an independent reference source can also be selected for ADC2.
