The instrumentation amplifier IC uses an adjustable gain differential amplifier with buffered inputs to amplify the readings from an analog sensor using a wheatstone bridge such as a load cell or pressure transducer. The amplifier supply voltage was chosen to match that of the pressure transducers it is intended to be used with.

Questions
How big is the Instrumentation Amplifier PCB?
It measures 24.1 × 34.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Instrumentation Amplifier use?
13 parts, built around the AD623ARZ-R7 and 2043-1X04G00DAU. 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 Instrumentation Amplifier KiCad files?
From the cacost12/SDR-Instrumentation-Amplifier-PCB repository on GitHub, at the commit this page was made from: the board is src/Instrumentation-Amplifier.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Instrumentation Amplifier design in my own project?
Its repository states no licence, so its author keeps all rights: ask cacost12 before reusing the design.
