Part Number: ADS1299
We intend to use the AF7, AF8, FP1, FP2, and FPZ potential electrodes on the forehead for EEG-related tests. However, this involves electrode reuse. FP1 and FP2 will be used as BIAZ electrodes during EEG testing and will also be compatible as electrical stimulation electrodes. FPZ will serve as a reference electrode during EEG testing and will also be compatible with FP2 for EDA testing. See the attached "Power Supply and System Block Diagram" section for a detailed block diagram.
1. When reusing EEG electrodes with electrical stimulation and EDA testing electrodes, what key performance indicators should be monitored for the switching switch?
2. Please review the current power tree and system block diagram to see if any adjustments are needed.
3. Please review the schematic diagram for any issues.
4. AF7 and AF8 EEG testing supports both sequential and reference lead configurations. Please check the schematic diagram to see if any adjustments are required.
