Query on AD5429 - 8 bit DAC

Hi,

 

I need a variable differential reference which can generate voltage ranges from -10V to +10V. So, I thought of using a DAC to generate those variable references.

Since I need a differential reference I have selected a 2 channel DAC, AD5429. While choosing the DAC I used the parametric table available in your website. It is mentioned that AD5429 has a output swing of 20V p-p. But in the datasheet, an external amplifier is used to generate +/-10V output. It is also mentioned that the reference can be +/-10V.

 

can I get bipolar +/-10V output from each channel of this DAC. And also suggest a way to generate -10V reference without affecting the precision of DAC.

 

Thanks,

Jebas.
