DAC Design with PCM1795 and STM32
yes please
Thought for 5 sec
I’ll rebuild this as a real IC-level DAC schematic: PCM1795 pins, three OPA1612 dual op-amps, I/V parts, differential outputs, regulators/connectors, then verify ERC before stopping at the schematic stage.
Thought for 35 sec
I found the previous connector-only blocks. I’m removing those and replacing them with actual ICs and analog-stage components now.
Worked for 10 mins 1 sec
Rebuilt the project as a real IC-level schematic instead of connector blocks: PCM1795, 3× OPA1612, LT3042 3.3 V/5 V rails, I/V feedback networks, differential output stage, RCA outputs, and power/input headers are now present and wired. ERC checks are currently clean for the checks run, and the project spec was updated.
Open items:
- The PCB layout is not done yet; per workflow, this is the schematic checkpoint before layout.
- The PCM1795 library symbol/footprint must be visually checked against the TI datasheet pinout before fabrication.
- STM32F407 exact I2S/SPI GPIO mapping is still your next firmware/pinout decision.
Suggested next steps:
- Review the schematic view and confirm it now looks like the detailed circuit you expected.
- I can next create the physical PCB placement with DAC + OPA stages tightly clustered.
- After placement approval, I can route the board with low-noise analog layout rules.
