ECG MUX Tab

The ECG MUX tab (Figure 7) congures the internal ECG switches that precede the ECG ampliers and lters. Internal

calibration and verication functions of the IC are also accessible from this tab. In order to measure external ECG

signals, the ECGP Switch and ECGN Switch in the Switches block must be set to Connected. The switches should

be set to Isolated if Calibration Test Voltage is used. It is also recommended to have Resistive Lead Bias Enable

set to ECG Bias, Resistive Bias Value set to 100MΩ, Positive Input Bias Enable and Negative Input Bias Enable

set to Connected. DC Lead-O󰀨 Check, ULP Lead-On Check, and Calibration Test Voltage functionalities are detailed

further in depth in the MAX30001 data sheet.
