Excuse me, for the FDC2214 acquisition chip, usually the collection of capacitors requires voltage and frequency to be applied to the capacitor device. What parameter is the frequency of the power supply applied to the capacitor device in this chip.
电容两端的电压即为sensor的差分输入电压，可以看下datasheet中的电气参数，幅值范围典型值为1.2Vpp~1.8Vpp。
sensor的驱动频率范围为0.01M~10Mhz。
