An OP200EZ is a highly versatile, precision operational amplifier that is used in many applications for linear amplification of signals. It is a type of instrumentation amplifier, which utilizes a differential input stage and high-gain feedback circuit to deliver highly accurate and reliable performance. In addition, the OP200EZ has excellent noise performance and very low distortion, making it ideal for applications such as voltage and current regulation, noise cancelling, and precision measurement. This article will discuss the application field and working principle of the OP200EZ.

Applications

The OP200EZ can be used in many different types of applications, such as audio amplification, DC offset correction, transducer signal conditioning, analog-to-digital converter applications, and instrumentation systems. It is particularly well-suited as a buffer amp, providing a low-impedance voltage gain stage for low-level signals. It can also be used as a driver for display, actuator or RF amplifiers. The OP200EZ is especially well-suited for use in high-precision, low-bandwidth applications, due to its high common-mode rejection ratio and excellent linearity.

Working Principle

At the heart of the OP200EZ is the differential input stage, which utilizes two pairs of bipolar transistors to accurately convert an input voltage into a differential voltage. The differential voltage then passes through a voltage-gain block, where it is amplified and buffered before it is fed into the high-gain feedback loop. The feedback loop contains an offset voltage reference, precision amplifier, and active compensation components. This enables the OP200EZ to deliver very stable and accurate results, even over extended time periods. The output of the feedback loop is then amplified and passed through a buffer before it is output as a voltage or current.

Conclusion

The OP200EZ is a highly versatile, precision operational amplifier that is suitable for many applications. It has excellent noise performance and very low distortion, making it ideal for precision signal conditioning and instrumentation applications. It has a differential input stage and high-gain feedback loop that enable it to deliver highly accurate and reliable performance. In addition, it is well-suited as a buffer amp, providing a low-impedance voltage gain stage for low-level signals. This makes the OP200EZ a versatile and reliable choice for many applications.
