Implementation of the standard 15µs/50µs digital de-emphasis filter response, Figure 20, requires re-
configuration of the digital filter to maintain the proper filter response for 32, 44.1 or 48 kHz sample
rates.
NOTE: De-emphasis is only available in Single-Speed Mode.

The device will enter a low-power state when this function is enabled. The power-down bit defaults to
‘enabled’ on power-up and must be disabled before normal operation can occur. The contents of the
control registers are retained in this mode.
