What is the actual capacitance of typical breadboard contacts? It’s not in the datasheet, so Dave decides to measure it. It is well know that breadboards are not suitable for high frequency work due to the stray capacitance between contacts, but how bad is it really?

Dave breadboards a precision 1A current source circuit and finds that even the application reference circuit doesn’t work as expected. Showing that you can’t just blindly trust that datasheet application circuit will work first go. LTC6655  Forum HERE   Podcast: Download

      So, HP, err, I mean Agilent, have a new name – Keysight Technologies. That’s as big a news as it gets in the electronics industry, but as Julius Sumner Miller said, why is it so? Does anyone care if they change their name? You bet! In 1939 Bill Hewlett …
