Input protection (again)
Hi all, finally got around to testing these LND150's back to back (in series) as input protection. After playing with my signal generator, I plugged this into the AC wall outlet. (with a remote...

Relay vs. FET's
So, is my argument weak? One of our products needs to interface to various, unknown, ever-changing, commercial building alarm panels. Our designer is using opto-isolators to drive a pair of N-Channel...

Make LTSpice report an error
I'd like a way to make LTSpice report an error if one of my sub-circuits detects an invalid condition. For example, I often simulate a PIC by representing it as a sub-circuit that applies signals to...

Memory
I'm rebuilding an older server to act as my compile farm. So, digging through my box of RAM to see what I can find that fits the bill. The documents for the machine indicate (emphasis mine): DIMMs...

Another op-amp stability question (LT1677)
Tim W.'s question about the influence of resistance in the feedback path of a voltage follower reminded me of a similar problem I ran into a while back. I've used LT1677s as an integrator in several...
