Instrumentation amplifiers are special-purpose differential amplifiers whose inputs are operating at low levels and therefore need special design considerations. The NJM4741M amplifier is the first of a new generation of practical instrumentation amplifiers whose working principle is based on a buffer amplifier circuit. This innovative concept makes the NJM4741M a unique, versatile and unique amplifier.

Instrumentation amplifiers are used to give very precise, low level voltage gain such as in low level sensors or to amplify small signals. They are typically used in medical imaging equipment, measurement systems and process controls where accuracy and precision requirements are demanding. The NJM4741M is designed to be used in applications requiring more than one gain setting and it is capable of providing high accuracy, low distortion, and low noise even in challenging environments. The NJM4741M offers excellent common mode rejection, temperature stability, and high speed operation.

The NJM4741M working principle is based on a buffer amplifier circuit which consists of a differential input stage, a feedback loop, and a buffer amplifier. Input signals to the differential input stage are treated as differential signals and passed through a feedback loop to the buffer amplifier. The output response of the buffer amplifier is then adjusted to the desired output. The buffer amplifier also serves as a high gain buffer for protection of the amplifier from high voltage/current transients and as a buffer for preventing input saturation. The NJM4741M provides constant voltage gain and is designed for operation from DC to 1MHz.
