EVAL-AD2428WC1BZ A²B Evaluation Board User Guide Engineer-to-Engineer Note EE-420
●This evaluation board provides A2B bus-powered slave node functionality for an A2B network, including support for PDM microphone input. Bus-powered slave nodes derive power from the bias voltage on the A2B wires.
The EVAL-AD2428WC1BZ board’s four digital INMP621 MEMS microphones with PDM output can feed the upstream or downstream slots on the A2B bus. Adding multiple microphone signals increases the acoustic dynamic range. This four microphone array also lends itself well to static or adaptive beamforming techniques used to introduce directionality to the otherwise omnidirectional MEMS microphones.
●For the board schematics, assembly/layout files, and bill of materials (BOM), see the EVAL-AD2428WC1BZ Hardware Design Files ZIP archive associated with this EE-note.
