DAC-to-DAC Crosstalk

DAC-to-DAC crosstalk is the glitch impulse transferred to the

output of one DAC due to a digital code change and subsequent

output change of another DAC. This includes both digital and

analog crosstalk. It is measured by loading one of the DACs

with a full-scale code change (all 0s to all 1s or vice versa) with

LDAC low and monitoring the output of another DAC. The

energy of the glitch is expressed in nV-s.

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)

Total harmonic distortion 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.
