Channel 0 to 7.
Analog voltages are applied to these inputs for A/D conversion. In single-ended
configuration, these inputs are referenced to Analog Ground. In pseudo-differential configuration, these
inputs are considered “high side” and are referenced to PD.
Channel 0+ to 7+.
Differential “high side” voltages are applied to these inputs for A/D conversion. Each
input is referenced to a corresponding differential “low side” input.
Channel 0– to 7–.
Differential “low side” voltages are applied to these inputs for A/D conversion. Each
input is referenced to a corresponding differential “high side” input.
