EV_T5838-FX2

EV_T5838-FX2 is an evaluation board that allows quick evaluation of the performance of T5838 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 0.1μF supply bypass capacitor and a 50 ohm series resistor on the data line.

• High quality mode (-41dBFS +/- 1): 310µA typ supply current and 68dB SNR
• Low power mode (-26dBFS +/- 1): 120µA typ supply current, 65dB SNR
• Ultrasonic mode (-41dBFS +/- 1): 500µA typ supply current, 68dB SNR
