I just don't see the connection from SMD components to Windows 10, but I'm a boring engineer not on drugs. Maybe THC helps creating such interesting connections. I don't say this is a bad thing :clap:. And yes, I "trust" simulators. Just don't blindly. They are tools you need to understand. Really helpful tools. Designing without one is also a masochistic act. |
| Jan Audio:
So you simulate and send to factory ? Sounds breadboardless. I agree that my designs take at least a full year to complete, i better call it patience. |
| Siwastaja:
Prototyping highly recommended. Fully simulating for all aspects takes more time than using the best tool for the job, which often is a physical prototype. I personally do not like solderless breadboards, they are source of extra problems I don't want; even if you use highest-quality 3M breadboards and be careful not to damage them, they greatly limit the types of components you can insert. Instead, learn to be proficient with soldering iron, then you can quickly prototype any types of parts, SMD and THT included, without wonky and unreliable connections. Google "Manhattan style prototyping" for pictures. Sometimes there is no work for a SPICE simulator. For example, a circuit running an MCU interfacing a digital temperature sensor and showing the number on 7-segment display, nothing interesting in analog domain going on you would want to simulate. With such simple example, if you are even a bit experienced, you won't need to Manhattan prototype it, just draw and order 5pcs PCBs, 90% chances you can just start producing it as-is, 10% you made some stupid mistake which you'll fix to the final revision. Patience is good. Quick iteration cycle is still good even if you have a lot of time in your hands - you can run more cycles and get even better product. |

Quite a few different types are in stock. Not sure how long-lived the link to the search results will be, but here it is: https://www.mouser.de/Semiconductors/Integrated-Circuits-ICs/Audio-ICs/Audio-D-A-Converter-ICs/_/N-6j741Zgjdhub?P=1z0yhi1Z1z0z5fdZ1z0z7v5 Edit: Oh, and did I mention 130 audio DACs in SSOP/TSSOP packages, which can be drag-soldered by hand with a regular iron as well? |
