7.2 Transient Response Parameters

The transient response of the TMCS1100-Q1 is impacted by the 250kHz sampling rate as defined in Transient Response. Figure 7-2 shows the TMCS1100-Q1 response to an input current step sufficient to generate a 1V output change. The typical 4µs sampling window can be observed as a periodic step. This sampling window dominates the response of the device, and the response has some probabilistic nature due to alignment of the input step and the sampling window interval.
