Fig. 8-6-1. Bypass Mode

In bypass mode, the output after ADC prefilter and the output after DAC postfilter are swtiched by the analog

switch. The popping noise occurs at switching due to the difference of these filter's reference voltages

(500mV). Therefore, the countermeasure against the noise, such as the system muting, is required when using

this mode.
