The working principle of 65863-081FLF is based on differential amplifier topology that consists of cross-coupled differential input stage with an output stage. The differential input stage has an improved differential linearity and low noise behaviour due to the use of a differential pair and an isolation amplifier. The differential pair is composed of a current mirror with an integrated level shift circuit. The level shift circuit isolates the common mode from the differential output and prevents noise from propagating through the system. The output stage is a voltage-to-current converter which converts the differential voltage signal into a current signal that is then used to drive the load. The voltage-to-current converter also provides a compensator which ensures that the output current of the device remains stable over a wide range of ambient temperatures.

In conclusion, the 65863-081FLF is a versatile, accurate, and reliable electronic instrument used in a variety of applications. Its differential input stage, low power consumption, and high noise rejection ratio make it ideal for precision control systems in a wide range of industries including automotive, avionics, and industrial applications. Its working principle is based on differential amplifier topology which allows for high precision operation over a wide range of ambient temperatures and provides a compensator to ensure that the output current remains stable.
