DAC Output Noise Density
Output noise density is defined as
internally-generated random noise. Random noise is
characterized as a spectral density (nV/√Hz). It is
measured by loading the DAC to midscale and
measuring noise at the output.
DAC Output Noise
DAC output noise is defined as any voltage deviation
of DAC output from the desired value (within a
particular frequency band). It is measured with a DAC
channel kept at midscale while filtering the output
voltage within a band of 0.1Hz to 10Hz and
measuring its amplitude peaks. It is expressed in
terms of peak-to-peak voltage (V_pp).

Full-Scale Range (FSR)
Full-scale range (FSR) is the difference between the
maximum and minimum analog output values that the
DAC is specified to provide; typically, the maximum
and minimum values are also specified. For an n-bit
DAC, these values are usually given as the values
matching with code 0 and 2ⁿ.
