Effective April 1 2014, this product part number will change from EVAL-ADMP421Z-FLEX to EVAL-INMP421Z-FLEX. This is a name change only - all specification will remain the same. Parts may be purchased by either part number until April 1. No parts shall be shipped after April 30th with the older part number. The name change is a requirement of the acquisition of the MEMS Microphones by InvenSense.
The InvenSense EVAL-INMP421Z-FLEX is a simple evaluation board that allows quick evaluation of the performance of the INMP421 MEMS microphone. The small size and low profile of the flexible PCB enable direct placement of the microphone into a prototype or an existing design for an in-situ evaluation.
