Connect the signal output pin UF_DAC and GND to CH1 of the oscilloscope properly using the
probe;
Set the trigger type to “Edge”, the trigger mode to “Auto” and the vertical scale to “1V”; adjust
the vertical position and trigger level to appropriate values to make the oscilloscope trigger
stably. The analog signal is as shown in the figure below. This signal is the converted and
unfiltered analog signal and the waveform has apparent “steps” as shown in the figure below.

Connect the signal output pin DAC_OUT and GND to CH2 of the oscilloscope properly using the
probe;
Set the vertical scale to “1V” and adjust the vertical position and trigger level to make the
oscilloscope trigger stably. The analog signal is as shown in the figure below. This signal is the
converted and filtered analog signal and the waveform is relatively smoother as shown in the
figure below.
