ADT7518
DAC-to-DAC Crosstalk
This 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 and 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
This is the difference between an ideal sine wave and its atten-
uated 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, expressed in dB.
This term is used to describe the ADT7518 cycling through the
available measurement channels in sequence, taking a measure-
ment 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.
