FLT: Digital Filter Rolloff Control (DAC)

Default value: 0

FLT = 0 Sharp rolloff (Default)

FLT = 1 Slow rolloff

The FLT bit allows the user to select the digital filter roll-off that is best suited to their application. Sharp and Slow

filter roll-off selections are available. The filter responses for these selections are shown in the Typical

Performance Curves section of this data sheet.

DMF[1:0]: Sampling Frequency Selection for the De-Emphasis Function (DAC)

Default value: 00

DMF[1:0] De-Emphasis Sampling Rate Selection

0 0 44.1 kHz (default)

0 1 48 kHz

1 0 32 kHz

1 1 Reserved

The DMF[1:0] bits are used to select the sampling frequency of the digital de-emphasis function when it is

enabled.

DMC: Digital De-Emphasis Function Control (DAC)

Default value: 0

DMC = 0 De-emphasis disabled (default)

DMC = 1 De-emphasis enabled

The DMC bit is used to enable or disable the digital de-emphasis function. See the plots shown in the Typical

Performance Curves section of this data sheet for frequency characteristics.

ZREV: Zero-Flag Polarity Select (DAC)

Default value: 0

ZREV = 0 High for zero detect (default)

ZREV = 1 Low for zero detect

The ZREV bit is used to control the polarity of zero flag pins.

AZRO: Zero-Flag Function Select (DAC)

Default value: 0

AZRO = 0 ZEROL: L-ch ZERO detection (default) ZEROR: R-ch ZERO detection (default)

AZRO = 1 ZEROL: L and R ZERO detection ZEROR: L and R ZERO detection

The AZRO bit is used to select the function of zero flag pins.
