The output impedance is low, ensuring a low noise floor and high dynamic range.

The working principle of the MAX4382ESD+T is based on the galvanic isolation principle. The amplifier is formed by a p-channel metal-oxide semiconductor field-effect transistor (MOSFET) and an n-channel MOSFET in conjunction. The applied input voltage difference between the two MOSFETs increases the voltage between the source and the drain, reducing the amount of current flowing through the semiconductor. This further increases the resistance and decreases the noise. The output current is then managed based on the gate voltage.

The MAX4382ESD+T is suitable for use in a variety of instrumentation, buffer amp and operational amplifier applications such as high accuracy measurements, filtering, switching, isolating and buffering signals. The combination of low input offset voltage and high speed makes it ideal for a wide range of commercial, industrial and instrumentation applications. It is perfectly suited for sensor systems, medical and industrial control applications.
