Φ Datasheet Q&A.
Drop a datasheet PDF (or paste the relevant section) and ask a question. You get the answer and the exact passage it came from — never an uncited guess.
How Φ Datasheet works
Most “chat with PDF” tools mangle datasheets — they flatten the parameter tables, lose the min/typ/max columns, and drop the conditions footnotes that change the answer. Φ Datasheet keeps the document intact and answers only from it, always returning the exact quoted passage so you can verify in one glance.
What’s behind it
Claude reads the datasheet (native PDF understanding for uploads, or the pasted text), answers under a strict system prompt that forbids answering from general knowledge, and returns a structured result: the answer, a confidence level, and one or more verbatim citations with a location hint. The whole datasheet is sent as a cached prefix, so repeated questions about the same part are fast and cheap.
What it won’t do
- It won’t invent a spec that isn’t in the document — if it’s absent, it says so and marks confidence “low”.
- It isn’t a substitute for reading the abs-max ratings yourself before you commit silicon.
- v1 answers one datasheet at a time. Cross-part comparison (RAG over many datasheets) is the documented next step.
Why cited, always
An EE can’t act on an uncited number. Every answer shows the passage it came from — if we can’t quote it, we don’t claim it.
