Notes

1.

The ADC inputs can be used in a 2 V (RMS value) input signal configuration when a resistor of 12 kΩ is used in series with the inputs and 1 or 2 V (RMS value) input signal operation can be selected via the Input Gain Switch (IGS).

  • 2.

    The ADC input signal scales inversely proportional with the power supply voltage.

  • 3.

    The DAC output voltage scales linear with the DAC analog supply voltage.
