(1) Slew Rate is measure from 10% to 90% of transition when the output changes from 0 to full scale.
(2) 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. It is specified with a full-scale code change on the SDI bus
(that is, from all 0s to all 1s and vise versa).
(3) Reference input resistance is code-dependent, with a minimum at 8555h
