Front-End Analógico Design
Worked
Thought
Work completed
- Updated project description to include a clear statement of analog front-end goals with hashtags (item 1).
Tasks remaining
- Design and add system architecture diagram (2.1–2.2)
- Select and add OPA2347 dual op-amp (3.1)
- Select and add ADS8320 ADC (3.2)
- Verify/update ATtiny85 metadata (3.3)
- Add passives and protection components (4.1–4.4)
- Implement all net connectivity (5.1–5.7)
- Establish ground strategy (6.1–6.3)
- Review schematic completeness (7.1–7.3)
- Prepare PCB layout parameters (8.1–8.4)
- Pause for input on signal range/bandwidth/supply/sensor type (9)
Success criteria status
- No criteria met yet; schematic still lacks component additions, connectivity, and ground strategy.
Next recommended step
Proceed with creating the system architecture diagram (plan step 2): draft a mermaid diagram showing Sensor → OPA2347 (buffer & guard) → ADS8320 → ATtiny85 and add it to the “System Architecture” project property.
