Ξᴅᴅʏ ✘ on Instagram: "📌 INSTRUMENTATION AMPLIFIER An instrumentation amplifier (INA) is a type of amplifier that amplifies low-level signals while rejecting noise and interference. It's often used to amplify signals from sensors like strain gauges. 🔸️How it works INAs have high input impedance and low output impedance They amplify the difference between two input lines, ignoring any common-mode noise They have a high common-mode rejection ratio (CMRR) They have a high open-loop gain They have
