ADAS1000-4: Minimal reference schematic for basic ECG acquisition and QRS visualization

Hello,

I am currently developing a small ECG device as part of my final thesis and I selected the ADAS1000-4 because it seems to be a very capable solution for compact ECG acquisition.

At the moment, I am not trying to build a full advanced medical system yet. My immediate goal is much simpler: I want to establish a minimal and technically correct hardware baseline that allows me to acquire ECG signals and visualize a clear QRS complex.

I have already started my own schematic draft based on the datasheet, including the basic ECG input path, protection concept, clocking, and power supply considerations. However, before I continue too far, I would like to ask whether Analog Devices can provide or point me to any of the following specifically for the ADAS1000-4:

• a minimal reference schematic for basic ECG acquisition
• an evaluation board schematic
• an application note with a proven front-end example
• or any recommended minimal hardware configuration for simply acquiring ECG data and displaying a visible QRS complex

At this stage, I do not need a complete production-ready system. A known-good minimal reference design for basic ECG signal acquisition would already be extremely valuable and would help me build a solid foundation for my thesis project.

If helpful, I can also share my current schematic draft for context.

Thank you very much for any guidance.

Best regards,
Atakan
