Internal and external reference voltage for DAC

[Somil]

Hi

For example: If we are using +10V as the internal reference voltage, the range of the DAC would be -10 to +10V. But if the signal goes only from -5 to +5 V, the resolution of DAC is not getting maximized. To maximize the Resolution, an external refernce voltage of +5V can be given. Now the range of the DAQ will be -5V to +5V, same as that of the signal..

What is internal and external reference voltage for DAC ?????

Hi,

you're better post this question on the "multifunctional DAQ" section, quoting the P/N of your device, as well as your programming language
