demonstrates a simple solution. The 1800 pF capacitors in the low-pass filter should be C0G or equivalent
to avoid distortion issues

Analog Input Configuration for 2 VRMS Input Levels
The CS5346 can also be easily configured to support an external 2 VRMS input signal, as shown in
Figure 13. In this configuration, the 2 VRMS input signal is attenuated to 1.5 VRMS at the analog input with
the external 12 k resistor and the input impedance to the network is increased to 48 k. The PGA gain
must also be configured to attenuate the 1.5 VRMS at the input pin to the 1.0 VRMS maximum A/D input level
to prevent clipping in the ADC.
