ANALOG INPUT BANDWIDTH is a measure of the frequency
at which the reconstructed output fundamental drops
3 dB below its low frequency value for a full scale input. The
test is performed with fIN equal to 100 kHz plus integer multiples
of fCLK. The input frequency at which the output is −3
dB relative to the low frequency input signal is the full power
bandwidth.
APERTURE JITTER is the variation in aperture delay from
sample to sample. Aperture jitter shows up as input noise.
APERTURE DELAY See Sampling Delay.
BOTTOM OFFSET is the difference between the input voltage
that just causes the output code to transition to the first
code and the negative reference voltage. Bottom Offset is
defined as EOB = VZT–VRB, where VZT is the first code transition
input voltage and VRB is the lower reference voltage.
Note that this is different from the normal Zero Scale Error.
CONVERSION LATENCY See PIPELINE DELAY.
CONVERSION TIME is the time required for a complete
measurement by an analog-to-digital converter. Since the
Conversion Time does not include acquisition time, multiplexer
set up time, or other elements of a complete conversion
cycle, the conversion time may be less than the
Throughput Time.
DC COMMON-MODE ERROR is a specification which applies
to ADCs with differential inputs. It is the change in the
output code that occurs when the analog voltages on the two
inputs are changed by an equal amount. It is usually expressed in LSBs.
