Analog Crosstalk

Analog crosstalk is the glitch impulse transferred to the output

of one DAC due to a change in the output of another DAC. It is

measured by loading one of the input registers with a full-scale

code change (all 0s to all 1s and vice versa) while keeping

LDAC high. Then pulse LDAC low and monitor the output of

the DAC whose digital code was not changed. The area of the

glitch is expressed in nV-s.

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 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.
