Single-Ended or Differential Analog Input 6.
Single-Ended or Differential Analog Input 7.
Single-Ended or Differential Analog Input 8.
Single-Ended or Differential Analog Input 9.
Single-Ended or Differential Analog Input 10.
Ground Voltage Reference for the ADC. For optimal performance, the analog power supply
should be separated from IOGND and DGND.
Bias Point or Negative Analog Input of the ADC in Pseudo Differential Mode. Must be connected
to the ground of the signal to convert. This bias point must be between 0 V and 1 V.
DAC0 Voltage Output/Single-Ended or Differential Analog Input 12. DAC outputs are not
present on the ADuC7027.
DAC1 Voltage Output/Single-Ended or Differential Analog Input 13. DAC outputs are not
present on the ADuC7027.
DAC2 Voltage Output/Single-Ended or Differential Analog Input 14. DAC outputs are not
present on the ADuC7027.
DAC3 Voltage Output/Single-Ended or Differential Analog Input 15. DAC outputs are not
present on the ADuC7027.
