AD5724/AD5734/AD5754 channel mix of output range

Datasheet is clear -  The range can be set to +5 V, +10 V, +10.8 V, ±5 V, ±10 V, or ±10.8 V.

But can the range be different per channel?

If yes - so there are no restrictions apart from the fact that the supply voltage should be sufficient for all selected ranges (Highest one). Right?

The selection "BIN/2sComp" is obviously common for all channels.

  • Hi, 

    Yes, the range can be different per channel as seen from Table 21 on the d/s, the specific DAC channel address is set for an output range selection write. You are also correct, the supply voltage should be considered for the highest range. 

    The BIN/2sComp sets the coding scheme only for the bipolar ranges. If the range selected is unipolar, it is automatically straight binary coding. 

    Best regards,


  • Thanks Ian, Just what I needed to know.

    The place you point out is as far as I can see, the only place in the datasheet where this important detail can be read. So it requires study of the low level register interface! Not the place you want to study when scanning the market for suitable DAC's.

    So I would argue that this should be much more clearly stated in the "General description" by updating: 

    Nominal full-scale output range is software-selectable from +5 V, +10 V, +10.8 V, ±5 V, ±10 V, or ±10.8 V.

    to read something like:

    Nominal full-scale output range is software-selectable per channel from +5 V, +10 V, +10.8 V, ±5 V, ±10 V, or ±10.8 V.

    No point in hiding such an asset.

  • Hi, 

    This is on-point. Just a few words added to the description could save users a lot of time browsing through the d/s. Thanks. I will put a note on this for future datasheet revisions.
