The T5837 is a digital PDM MEMS microphone. This user guide provides information on how to use the flexible evaluation board for this part, EV_T5837-FX2.
This is a simple evaluation board that allows quick evaluation of the performance of PDM MEMS microphones. The small size and low profile of the flexible PCB enables direct placement of the microphone into a prototype or an existing design for an in situ evaluation. The evaluation board consists of a bottom port microphone soldered to a flexible PCB with an edge connector. Other components on the board are a 0.1 μF supply bypass capacitor and a 50 Ω series resistor on the data line. The flex edge is an 8 position 0.5mm pitch connector which mates to a standard connector such as Kyocera (MPN 046288008000846+, Digikey PN 478-5454-1-ND) or Molex (MPN 0527450897, Digikey PN WM3772TR-ND).
