My question is concerning the ADAS1000-1. There are certain electrode input ranges usually from 0.3V to 1.6V I believe. Does that mean we would need to implement an amplifier before sending the ECG signal to the ADAS? Just because an ECG signal has voltage of 1mV-3mV. Also would you recommend against including an amplifier and analog bandpass filter before sending the ECG signal to the ADAS? I know the ADAS1000 has an internal gain but just wanted to check.
Hi. No, you can directly connecting electrode to ADAS inputs. Internal filters is Ok and you don't need external filters. Use good cable and pads to get better result. If use isolated power and communication or battery as a power supply, the noise reduced significantly.
