DAC-to-DAC Crosstalk
DAC-to-DAC crosstalk is the glitch impulse transferred to the
output of one DAC in response to a digital code change and
subsequent analog output change of another DAC. It is measured
by loading one channel with a full-scale code change (all 0s to
all 1s and vice versa) using the write to and update commands
while monitoring the output of another channel that is at mid-
scale. The energy of the glitch is expressed in nV-sec.
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 (THD)
THD 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; THD is a measurement of the harmonics
present on the DAC output. It is measured in dB.
