The AD5752 consists of two DACs internally.

Can I use one DAC to generate unipolar voltage and another DAC for bipolar voltage simultaneously?

It is a dual channel DAC.



The voltage range applies to both channels. If you supply it with +-10V, then both channels can output voltages in the range of +-10V.

There's nothing that says you have to put out negative voltages, though.

You can send values to one DAC that always generate positive voltages. That's your "unipolar" output.

You can send values to one DAC that generate positive and negative voltages - that's your "bipolar" output.

Or, you can send "bipolar" signals to both DACs.

If you only need positive output, then you can supply it from a single supply, and not be able to generate negative voltages at all.

  • \$\begingroup\$ @ JRE So can i generate both unipolar and bipolar voltages from each of the dac by suppllying bipolar supply voltage ? \$\endgroup\$ – mightybeard May 30 at 11:08
  • \$\begingroup\$ Yes. If you need a bipolar output, you must use a bipolar supply. \$\endgroup\$ – JRE May 30 at 11:09

  • \$\begingroup\$ Yes. As I said in the answer, you have to use a bipolar supply because you need a biploar output but you don't have to send bipolar data to both channels. \$\endgroup\$ – JRE May 30 at 11:21
  • \$\begingroup\$ @JREI am using AD5752 chip for new board design. I have provision for +12V supply for the DAC, but I am not sure about -12V supply for DAC. Should I go for some OP am based solution or any chips which convert +12V to -12V? \$\endgroup\$ – mightybeard Jun 3 at 5:05
