Front-End Analógico Design


Updated to: "Dual-Channel Analog Front-End with Active Shielding, 16-bit SPI ADC, and ATtiny85 Interface"

Defining system architecture diagram...

Started: Define the system architecture as a mermaid diagram showing: Sensor Input → OPA2347 (buffer & guard) → ADS8320 → ATtiny85 control; save diagram in “System Architecture” property and share with user.

Designing mermaid system architecture diagram...

0:27

Started: 2.1. Design the mermaid diagram showing Sensor Input → OPA2347 (buffer channel & guard channel) → ADS8320 → ATtiny85 control and add it to the “System Architecture” project property.

Worked

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.
