INSTRUMENTATION AMPLIFIER

Instrumentation Amplifier

• An instrumentation amplifier amplifies very low-level signals while rejecting noise and interference.
• Heartbeats, blood pressure, temperature, earthquakes, and so on are all examples. As a result, the following are the basic properties of a good instrumentation amplifier.
• The instrumentation amplifiers' inputs will have very low signal energy. As a result, the instrumentation amplifier must have a high gain and be precise.
• The gain should be easily adjusted with a single control, and it should have a high input impedance and a low output impedance to avoid loading.
• The instrumentation amplifier should have a high CMRR because the transducer output will usually contain common mode signals like noise when transmitted over long wires.
• It should also have a high Slew Rate to handle sharp rise times of events and provide the maximum undistorted output voltage swing.
