ADC Digital IIR Filter
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:
2 fourth-order Sigma-Delta converters enabling 2 separate channels that are identical in
functionality
2 gain stages for each channel, 1 of which is an analogue gain stage and the other is a digital gain
stage.
DAC Sample Rate Selection
Each DAC supports the following sample rates:
8kHz
11.025kHz
16kHz
22.050kHz
32kHz
