8.5.4 De-Emphasis Control (Bit 0)
Function:
Implementation of the standard 50/15
μ
s 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.
Figure 18
shows
the filter response.
NOTE:
De-emphasis is available only in Single-Speed Mode.

Mute Control - Address 06h
8.6.1 Auto-Mute (Bit 5)
Function:
When set, enables the Auto-Mute function.
Section 5.2.6 “Auto-Mute” on page 26
.
8.6.2 ADC Channel A & B Mute (Bits 4:3)
Function:
When this bit is set, the output of the ADC for the selected channel will be muted.
8.6.3 Mute Polarity (Bit 2)
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.
8.6.4 DAC Channel A & B Mute (Bits 1:0)
Function:
When this bit is set, the output of the DAC for the selected channel will be muted.
