Multiplying Bandwidth

The amplifiers within the DAC have a finite bandwidth. The

multiplying 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

attenuated 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,

for 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.
