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.
