Temperature Sensing, and GPIO Ports
Small-Signal Bandwidth
A small -20dBFS analog input signal is applied to an
ADC so 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 digitized conver-
sion result has decreased by -3dB. Note that the T/H
performance is usually the limiting factor for the small-
signal input bandwidth.
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.
