MAX9938HEBS+T Application Field and Working Principle

MAX9938HEBS+T is a linear instrumentation amplifier that enhances the features of its predecessor, the MAX9938HEBS+, while maintaining the same overall size, weight, and layout. It has a very low distortion and is suitable for any single-ended or differential input applications in audio and line levels.

Application Field

The MAX9938HEBS+T is ideal for applications that require a wide and flat frequency response, low harmonic distortion, and extremely low noise and crosstalk. It is designed for use in instrumentation and process control systems, precision data acquisition, audio, and video systems. Its low noise performance makes it suitable for driving low-level active filters such as switched-capacitor ones.

It is also suitable for applications that require a wide and flat frequency response, low harmonic distortion, and extremely low noise and crosstalk. In addition, the small size makes it suitable for high-density circuits, such as electronic test and measurement, where it can take up minimal space and provide high stability.

Working Principle

The MAX9938HEBS+T\'s overall principle is based on the concept of a bifilar winding. This method of winding produces an ideal voltage difference between the two input wires without any extra components. As the draw current is supplied to the input wires in a symmetric fashion, there is no need for extra components to provide a base current reference.

The operation of the MAX9938HEBS+T is governed by a combination of amplifying transistors and resistors. The transistors provide an amplification operation, amplifying the input voltage. The output voltage is controlled by two resistors, one of which is adjustable and one of which is fixed. The adjustable resistor is used to adjust the gain of the circuit. On the other hand, the fixed resistor is used to set the circuit\'s output impedance so that it can be matched to the load.

The MAX9938HEBS+T also features a common-mode voltage input, which is used to set an offset between the input lines. This offset is used to ensure that the output of the circuit stays at a steady voltage level even if there are variations in the input voltage. The common-mode voltage also helps to maintain a low noise floor when used in combination with the output impedance setting.

Conclusion

The MAX9938HEBS+T instrumentation amplifier is an excellent choice for applications that require high performance and accuracy. Its low noise and distortion-free operation, coupled with its small size and versatile design make it a perfect choice for applications involving precision data acquisition, audio, and video systems. Additionally, its widely adjustable parameters make it suitable for any type of application, making it ideal for applications not just within audio but in any other field that requires high performance and accuracy.
