Figure 35 shows an example waveform created by a Fluke Medsim 300B processed by the ADS1298 at a
data rate of 8kSPS. Using higher data rates increases power consumption because all channels must
sample at this data rate simultaneously; thus, the PACE buffers offer the flexibility to process PACE
signals separately from the ADS1298. The signal must be AC coupled to obtain the waveform\ shown
below.
