(2)

Slew Rate is measure from 10% to 90% of transition when the output changes from 0 to full scale.

(3)

Digital feedthrough is defined as the impulse injected into the analog output from the digital input. It is measured when the DAC output

does not change, CS is held high, while SCLK and DIN signals are toggled.
