F8377的这个时序图的问题



Ts/h 是采样保持时间 ,, 那转换的时间是哪个?? 怎么看出来是10.5个ADCclk周期的呢   

  • 这个图看不出来    不过你可以通过最下面标注的t  和  ADCclk计算出来周期个数

    前面是采样保持时间

  • 问个问题  conversion time  10.5个adcclk周期 指的是S/H的末端到结果锁存的这段时间吧

    The parameter tLAT is the time from the end of the S+H window until the ADC conversion results latch
    in the ADCRESULTx register. If the ADCRESULTx register is read before this time, the previous
    conversion results will be returned.   这里说 tLAT是从 采样保持结束到转换结果锁存到寄存器中去的时间,从图上看tLAT也不过3个adcclk周期,也不到10.5个啊 ,
