DAC7621: Performance specifications for the internal reference voltage

Part Number: DAC7621
Other Parts Discussed in Thread: DAC63004, DAC60501, DAC53701

Hi team,

The DAC7621 datasheet does not give a performance specifications (For example, accuracy\temperature coefficient, etc) for the internal reference voltage, can you help me confirm its performance specifications? Because the customer needs it

  • Hi Amy,

    The reference is internal and there is no option for an external reference, so the error of the reference just looks like output error.  We specify zero-scale error and full-scale output, so that will give you an idea for accuracy.  We do not specify any temperature coefficients for this device, so I cannot provide that value.

    I recommend you consider a more modern device, such as the DAC53701, DAC63004, DAC60501.
