SOFTMUTE

The digital muting function used in Software and Hardware mode applies a softmute with the

operating characteristics shown in Figure 19.

Figure 19 Soft Mute Operation

When the softmute is applied the output of the device will decay towards VMID with a time constant of

approximately 64 input samples. When the mute is released, either manually or automatically by the

chip, the output will restart immediately from the current input sample.

ANALOGUE MUTE

Analogue mute can only be used in software mode and will cause the output of the selected DAC to

perform an analogue mute that clamps the output of the DAC to VMID. This function is dependent in

the IZD bit which is described in section INFINITE ZERO DETECT, later.
