Mute Control - Address 06h
Function:
Implementation of the standard 50/15 µs digital de-emphasis filter on the DAC output requires reconfigu-
ration of the digital filter to maintain the proper filter response for 44.1 kHz sample rate.
the filter response. NOTE: De-emphasis is available only in Single-Speed Mode.
Function:
When set, enables the Auto-Mute function.
Function:
When this bit is set, the output of the ADC for the selected channel will be muted.
Function:
The MUTEA and MUTEB pins (pins 24 and 21) are active low by default. When this bit is set, these pins
are active high.
Function:
When this bit is set, the output of the DAC for the selected channel will be muted.
