The ADC contains 2 integrated anti-aliasing filters:
A long IIR filter suitable for music (>44.1kHz)
G.722 filter is a digital IIR filter that improves the stop-band attenuation required for G.722
compliance(which is the best selection for 8kHz / 16kHz / voice)

DAC
The DAC consists of:
Each DAC has a fourth-order Sigma-Delta converter.
Each DAC is a separate channel with identical functionality.
Each channel has an analog and a digital gain stage.
DAC Sample Rate Selection
Each DAC supports the following sample rates:
8kHz
11.025kHz
16kHz
22.050kHz
32kHz
40kHz
44.1kHz
48kHz
96kHz
DAC Gain
The DAC outputs have two gain stages, a digital stage followed by an analog stage. The digital gain varies
between-24 dB and 21.5 dB and the analog gain between 0 dB and -21 dB, giving a total range of -45 dB to 21.5 dB.
Calls connected by the VM stream automatically select the distribution of gain within the DAC for best
performance.Alternatively, the individual gain stages can be set.
