SBOS825D September 2019 – July 2021 TMCS1101
Propagation delay is the time period between the input current waveform reaching 10% of its final value and VOUT reaching 10% of its final value. This propagation delay is heavily dependent upon the alignment of the input current step and the sampling period of the TMCS1101, as shown for several different sampling window cases in Figure 8-3.
Response time is the time period between the input current reaching 90% of its final value and the output reaching 90% of its final value, for an input current step sufficient to cause a 1-V transition on the output. Figure 8-3 shows the response time of the TMCS1101 under three different time cases. Unless a step input occurs directly during the beginning of one sampling window the response time will include two sampling intervals.
