Abstract
A Microelectromechanical System (MEMS) microphone includes a printed circuit board, a MEMS die, and an integrated circuit. The MEMS die is disposed on a top surface of the printed circuit board. The integrated circuit is disposed at least partially within the printed circuit board and produces at least one output signal. The output signals of the integrated circuit are routed directly into at least one conductor to access pads at the printed circuit board and the access pads are disposed on a bottom surface of the printed circuit board that is opposite the top surface.
