electrode to cancel out DC and low frequency body interference.
The voltage at the VCM sense electrode is maintained at the
reference voltage set by RF1-RF2.
With the values shown in Figure 42, the ECG circuit performance
parameters are:
1. Supply Voltage Range = +2.4V to +5.5V
2. Total Supply Current Draw @ +5V = 500A (typ)
3. Common-Mode Reference Voltage (VCM) = V+/2
4. Max DC Input Offset Voltage = VCM ±0.18V to ±0.41V
5. Passband Gain = 425V/V
6. Lower -3dB Frequency = 0.05Hz
7. Upper -3dB Frequency = 159Hz
