(1) See the Bipolar Output Operation section for details.
(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.
