Description
Single-Ended or Differential Analog Input 4.
Single-Ended or Differential Analog Input 5.
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.
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.
Ground for the DAC. Typically connected to AGND.
3.3 V Power Supply for the DACs. Must be connected to AV
