EVAL-ADMP421Z-FLEX 評估板可快速評估采用 4.00 mm × 3.00 mm
封裝尺寸的 ADMP421 PDM 輸出
MEMS 麥克風的性能。柔性
印刷電路板 (PCB) 的小尺寸和薄型使得可以將麥克風直接放置到原型或現有設計中以進行現場評估。該評估板由底部端口麥克風和 0.1 uF
旁路電容器組成，焊接到帶有顏色編碼電線的柔性 PCB 上。可以通過連接兩個柔性板的 DATA 線，同時將其中一個的 L/R SELECT 線連接到 VDD，另一根連接到 GND，來評估立體聲 PDM 麥克風
說明
-
EVAL-ADMP421Z-FLEX, Evaluation Board allows quick evaluation of the performance of ADMP421 PDM output MEMS microphones in a package with 4.00 mm × 3.00 mm footprint size. The small size and low profile of the flexible printed circuit board (PCB) enable 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 and 0.1 uF bypass capacitor soldered to a flexible PCB with color-coded wires attached. Stereo PDM microphones can be evaluated by connecting the DATA wires from two flex boards, while tying the L/R SELECT wire of one to VDD and the other to GND
