Figure 31. DAC Waveform Does Not Reach the Peak When the Port

Is Connected to Ground

4. The purple waveform is the signal driven into the DAC. The teal waveform is the

voltage the ADC sees on the DAC pin. Since there is resistance between MAX11300

pin and board pin, the voltage observed by the ADC is not equal to the voltage on

the board output pin.

5. Remove the jumper wire between P1 and GND.

6. Keep the plot windows open.
