10 / 16 page ADMP521 Data Sheet Rev. A | Page 10 of 16 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.
