In our design ,we are using AD558 DAC to generate the output voltage 0 to 3.2V. According to datasheet ,it is possible to generate two output voltage ranges i.e 1) 0 to 2.56V 2) 0 to 10V. Please suggest the external circuit to generate the output voltage from 0 to 3.2V.
Hi,
You can re-scale the output voltage by using external resistors, as the example shown in figure 4.
Other approach (which will probably give you better results, in terms of tempco) is by adding an external gain stage.
