APPLICATIONS INFORMATION
INTERFACING WITH ANALOG DEVICES CODECS
The PDM output of the ADMP521 interfaces directly with
the digital microphone inputs on Analog Devices ADAU1361,
ADAU1761, and ADAU1781 codecs. See the connection diagram
shown in Figure 14, and refer to the AN-1003 Application Note
and the respective data sheets of the codecs for more details on
the digital microphone interface.
The CN-0078 Circuit Note describes the connection between these
codecs and a digital microphone. All configuration information
is the same for the ADMP521 as it is for the ADMP421.
