Table 10. IIR Highpass Digital Filters
Digital Filtering
The MAX9880A incorporates both IIR (voice) and FIR
(audio) digital filters to accomodate a wide range of
audio sources. The IIR fiilters provide over 70dB of
stopband attenuation as well as selectable highpass fil-
ters. The FIR filters provide low power consumption and
are linear phase to maintain stereo imaging.

FUNCTION
MODE
Digital Audio Filter Mode. Selects the filtering mode for the DAI1 DAC and ADC signal paths.
0 = IIR voice filters
1 = FIR audio filters
AVFLT
ADC Digital Audio Filter. Configures the highpass filters for the DAI1 signal path.
MODE = 0
Select the desired digital filter response from Table 10. See the frequency response graphs in the Typical
Operating Characteristics section for details on each filter.
MODE = 1
0x0 = DC-blocking filter disabled.
0x1 = DC-blocking filter enabled.
DCB
1 = DC-blocking filter for DAI2 enabled.
0 = DC-blocking filter for DAI2 disabled.
DVFLT
DAC Digital Audio Filter. Configures the highpass filters for the DAI1 signal path.
MODE = 0
Select the desired digital filter response from Table 10. See the frequency response graphs in the Typical
Operating Characteristics section for details on each filter.
MODE = 1
0x0 = DC-blocking filter disabled.
0x1 = DC-blocking filter enabled.
Table 9. Digital Filtering Register
Note: Register addresses listed are for I2C. To get the SPI address, add 0x200 with the following exception: Register 0xFF is not
accessible through SPI.
