DIGITAL CROSSTALK

Digital crosstalk is the energy of the glitch impulse transferred to

the output of one DAC at midscale in response to a full-scale

code change (from all 0s to all 1s and vice versa) in the input

is specified as the current peak current of the output glitch in μA.

For a voltage-output DAC, it is specified as the peak voltage of the

output glitch in μV. Both are measured on one DAC channel at a

time.

DAC-TO-DAC CROSSTALK

DAC-to-DAC crosstalk refers to the energy of the glitch impulse that

is transferred to the output of one DAC when a digital code change

is loaded into the DAC register of another channel, resulting in a

corresponding analog output change. For a current-output DAC,

this crosstalk is measured as the peak of the current output glitch

in μA. For a voltage-output DAC, it is measured as the peak of the

voltage output glitch in μV. Both measurements are taken during

a full-scale change on one DAC output, by writing directly to the

DAC register while monitoring the other DAC output, which is held

at midscale.

ANALOG CROSSTALK

Analog crosstalk refers to the glitch impulse transferred to the

output of one DAC when a digital code change is loaded into the

input register of another channel and its output is updated via

an LDAC transition. It is measured by applying a full-scale code

change (from all 0s to all 1s and vice versa) to the input register

of the active channel, performing an LDAC update, and monitoring

the output of the channel whose code remains unchanged. It is

expressed as the peak current in μA for a current-output DAC and

as the peak voltage in μV for a voltage-output DAC.
