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.
ADC Power-Supply Rejection
ADC power-supply rejection (PSR) is defined as the
shift in offset error when the power-supply is moved
from the minimum operating voltage to the maximum
operating voltage.
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 lin-
earity is unaffected by changes in the power-supply
voltage.
