Slew Rate

The device slew rate is a limitation in the rate of change of the

output voltage. The output slewing speed of a voltage output

DAC is typically limited by the slew rate of the amplifier used

at the output. Slew rate is measured from 10% to 90% of the

output signal and is expressed in V/μs.

Power-On Glitch Energy

Power-on glitch energy is the impulse injected into the analog

output when the AD5413 is powered on. Power-on glitch

energy is specified as the area of the glitch in nV-sec.

Digital-to-Analog Glitch Energy

Digital-to-analog glitch energy is the energy of the impulse

injected into the analog output when the input code in the

DAC output register changes state. Digital-to-analog glitch

energy is normally specified as the area of the glitch in nV-sec.

The worst case of the glitch typically occurs when the digital

input code is changed by 1 LSB at the major carry transition.

Glitch Impulse Peak Amplitude

Glitch impulse peak amplitude is the peak amplitude of the

impulse injected into the analog output when the input code in

the DAC output register changes state. Glitch impulse peak

amplitude is specified as the amplitude of the glitch in mV and

the worst case of the glitch typically occurs when the digital

input code is changed by 1 LSB at the major carry transition.

Digital Feedthrough

Digital feedthrough is a measure of the impulse injected into

the DAC analog output from the DAC digital inputs. However,

the digital feedthrough is measured when the DAC output is

not updated, which occurs when the LDAC pin is held high.

The digital feedthrough is specified in nV-sec and is measured

with a full-scale code change on the data bus.

Power Supply Rejection Ratio (PSRR)

PSRR indicates how the DAC output is affected by changes in the

power supply voltage.
