The Normal Electrode input on the MUX routes the inputs (VINP and VINN) differentially to the internal PGA, as Figure 11 illustrates. In this mode, an ECG, sine wave, or pulse generator may be connected to test the ADS1298.
Figure 34 shows a typical six-lead output when connected to a 5mVPEAK, 80BPM ECG signal.
