Isolation amplifiers are components with dual purposes of amplification & safety. It is equipped with a delta-sigma analog-to-digital (AD) converter which helps in detecting infinitesimal electric current & voltage fluctuation with high precision. It provides grounding, insulation, and data isolation by providing a barrier of electrical safety & electrical isolation. It protects the patients from leakage currents and also protects data acquisition components from common mode voltages. It is used for amplifying low-level signals in multi-channel applications. It may include isolated power supplies for both the output and input stages, or may use external or peripheral power supplies on each isolated portion. It is commercially available as hybrid integrated circuits made by numerous manufacturers. Some methods of providing isolation are optically isolated amplifier, transformer-isolated amplifier and capacitive isolation amplifier.
The key advantages are included high linearity, high gain stability & linearity, avoids device & radiated noise and conducted noise, improves patient safety, high common mode rejection ratio and high accuracy.
