Dear Team,
We have designed a PCB with ADAS1000 AFE for our patient monitor application.
For that we took ADAS1000SDZ EVK as a reference, in evaluation schematics six different respiration path options are available, as listed below. Among these, we require your guidance in selecting the most efficient respiration path for measuring the accurate respiration:
Path 1: Respiration drive using internal capacitor, respiration measurement using ECG path
Path 2: Respiration drive using internal capacitor, respiration measurement using ECG paths via the EXT_RESP path
Path 3: Respiration drive using internal capacitor, respiration measurement via EXT_RESP path
Path 4: Respiration drive using external capacitor, respiration measurement using ECG paths
Path 5: Respiration drive using external capacitor, respiration measurement using ECG paths via the EXT_RESP path
Path 6: Respiration drive using external capacitor, respiration measurement with external amplifier
We have tested Path 1 on the evaluation board, and it is working well. Our objective is to achieve efficient respiration output during cautery(ESD) on the PCB we have designed, which includes all respiration path options excluding Path 3. Could you please advise which path would be preferable for this requirement?
Kindly suggest the most suitable option among the remaining four respiration paths.
