VID = differential input voltage, VI = input voltage referenced to ADC VMID with IN– or AUX IN– connected to
ADC VMID. In order to minimize distortion, it is recommended that the analog input not exceed 0.1 dB below full scale.
§ For single-ended inputs, the analog input voltage should not exceed the supply rails. All single-ended inputs should be
referenced to the internal reference voltage, ADC VMID, for best common-mode performance.
