V 1
Power-supply rejection is defined as the shift in offset
error when the power supply is moved from the minimum
operating voltage to the maximum operating voltage.
where V 1 is the fundamental amplitude, and V 2 through
V 6 are the amplitudes of the first five harmonics.
Spurious-Free Dynamic Range
Spurious-free dynamic range (SFDR) is the ratio of RMS
amplitude of the fundamental (maximum signal
component) to the RMS value of the next largest
spectral component.
ADC Channel-to-Channel Crosstalk
Bias the ON channel to midscale. Apply a full-scale sine-
wave test tone to all OFF channels. Perform an FFT on
the ON channel. ADC channel-to-channel crosstalk is
expressed in dB as the amplitude of the FFT spur at the
frequency associated with the OFF channel test tone.
DAC Power-Supply Rejection
DAC PSR is the amount of change in the converter’s
value at full scale as the power-supply voltage
changes from its nominal value. PSR assumes the
converter’s linearity is unaffected by changes in the
power-supply voltage.

Intermodulation Distortion (IMD)
IMD is the total power of the intermodulation products
relative to the total input power when two tones, f 1 and
f 2 , are present at the inputs. The intermodulation prod-

Small-Signal Bandwidth
A small -20dBFS analog input signal is applied to an
ADC in such a way that the signal’s slew rate does not
limit the ADC’s performance. The input frequency is
then swept up to the point where the amplitude of the

Note that the track/hold (T/H) performance is usually

Full-Power Bandwidth
A large -0.5dBFS analog input signal is applied to an
ADC and the input frequency is swept up to the point
where the amplitude of the digitized conversion result
has decreased by -3dB. This point is defined as full-
power input bandwidth frequency.
DAC Digital Feedthrough
DAC digital feedthrough is the amount of noise that
appears on the DAC output when the DAC digital con-
trol lines are toggled.
