Isolation Amplifiers Market Definition
An isolation amplifier is a type of differential amplifier that includes galvanic isolation between its input and output sections. This isolation is achieved through magnetic, optical, or capacitive means, effectively preventing any direct electrical connection. The main purpose of an isolation amplifier is to transmit accurate analog signals while protecting the data acquisition system from high-voltage transients and eliminating the possibility of ground loops. These devices are essential in systems where different parts operate at different voltage levels or where common ground paths could introduce noise or safety risks.

Isolation amplifiers are used in various industries such as medical diagnostics, industrial automation, renewable energy, and telecommunications. In medical applications, for instance, they help ensure patient safety by electrically isolating monitoring instruments from patients. In industrial settings, they protect control systems from electrical surges and signal interference. Isolation amplifiers are characterized by parameters such as input impedance, gain accuracy, bandwidth, and isolation voltage. They can handle both DC and AC signals and are designed to provide high common-mode rejection ratios (CMRR) and minimal signal distortion. Their reliability and protective capabilities make them indispensable in high-performance electronic systems where safety and signal integrity are critical.
