有关LDC1000 Output Data Rate 输出数据速率问题

请问LDC1000 的电感输出数据速率 是否可控。是取决于写入寄存器的最小谐振频率,还是由实际的谐振频率决定?!

  • 手册(ZHCSBM0 –SEPTEMBER 2013) P12 那段话应该回答了你这个问题

    Output Data Rate
    Output data rate of LDC1000 depends on the sensor frequency, fsensor and 'Response Time' field in LDC Configuration register(Address:0x04).
    Output data rate=( fsensor)/(Response Time/3), Sample per second(SPS)
    Example: If fsensor=5Mhz and Response Time=192
    Output data rate= (5M)/(192/3)= 78.125 KSPS

  • 按照这文档,输出速率就是不可控的了。
