Questions
How big is the Differential amp PCB?
It measures 36.8 × 56.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Differential amp use?
27 parts, built around the AD8422AR and AD8609AR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Differential amp KiCad files?
From the visgence/differential_amp repository on GitHub, at the commit this page was made from: the board is differential_amp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Differential amp design in my own project?
Its repository states no licence, so its author keeps all rights: ask visgence before reusing the design.
