(1) TheDAC8830 output is unipolar (0 V to VREF). TheDAC8831 output is bipolar (±VREF) when it connects to an external buffer (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.
