A low-pass filter is a filter that passes low-frequency signals but attenuates (reduces the amplitude of) signals with frequencies higher than the cutoff frequency. The actual amount of attenuation for each frequency varies from filter to filter. It

Sigma-Delta audio DAC. Connect a RC lowpass filter to the pin to reduce noise and improve the audio quality.
