SmartSound One MEMS Microphone Evaluation Module

TDK InvenSense SmartSound One Microphone Interface Module is an all-in-one microphone interface module that enables rapid evaluation and development of TDK MEMS microphone solutions. Users can connect up to two edge connector Flexible Printed Circuit Boards (FPCBs) and select the audio output interface to record over USB and evaluate the performance of a particular application. SmartSound One features an EEPROM to load the factory default DSP program on power-up, making it a plug-and-play solution. There are two parallel signal processing paths for analog and digital microphones, which the user can select using the ‘mode’ button, which is routed through the DSP and the onboard USB audio codec to send audio data packets over USB. The board also features an array of configuration jumpers to set compatible microphones in either low-power or high-quality listening modes, as well as a level boost of up to +30dB of digital gain for the convenience of real-time signal monitoring.
