Multiplying Bandwidth
The amplifiers within the DAC have a finite bandwidth. The
m
ultiplying bandwidth is a measure of this. A sine wave on
the reference (with full-scale code loaded to the DAC) appears
on the output. The multiplying bandwidth is the frequency at
which the output amplitude falls to 3 dB below the input.
Total Harmonic Distortion
This is the difference between an ideal sine wave and its
a
ttenuated version using the DAC. The sine wave is used
as the reference for the DAC, and the THD is a measure
of the harmonics present on the DAC output. It is measured
in decibels.
Round Robin
This term is used to describe the ADT7316/ADT7317/
ADT7318
cycling through the available measurement
channels in sequence, taking a measurement on each
channel.
DAC Output Settling Time
This is the time required, following a prescribed data change,
fo
r the output of a DAC to reach and remain within ±0.5 LSB
of the final value. A typical prescribed change is from 1/4 scale
to 3/4 scale.
