LM124N Application Field and Working Principle

The LM124N is a series of operational amplifiers (opamp) produced by Texas Instruments that are designed for high gain versatile use. This article will cover the LM124N\'s application fields, working principle and characteristics of the opamp. The LM124N series is most commonly used as an instrumentation amplifier, but can also be used in a variety of other applications such as active filters, followers, and oscillators.

Application Field of the LM124N

The LM124N is most commonly used as an instrumentation amplifier, which is an electronic circuit that takes a input signal and amplifies it for the purpose of measuring or monitoring. It is preferred over a regular opamp in this application due to its high input impedance, low noise and high gain. The LM124N can also be used in a variety of other applications such as active filters, followers, and oscillators. The LM124N\'s low noise, high input impedance and low input bias current make it ideal for use in sensitive monitoring and measurement applications. The LM124N can also be used in audio applications, where it can provide high gain, low distortion and low noise.

Working Principle of the LM124N

The LM124N is an operational amplifier, which mean it takes in two input signals, one inverting and one non-inverting and amplifies the difference between the two signals. The LM124N has extremely high input impedance and low bias current, which allows it to process weak input signals with minimal error. The LM124N also features low noise and high frequency response, which make it well suited for use in high performance amplifier designs. The LM124N is also capable of operating on single and dual supplies, providing flexibility for a wide range of applications.

Characteristics of the LM124N

The LM124N has a slew rate of 13V/μs, a total harmonic distortion of 0.003%, a maximum common-mode range of �13V, a common-mode rejection ratio of 90dB and an input voltage noise of 10nV/√Hz. It is capable of operating over a temperature range of �40�C to 125�C, making it well suited for use in extreme temperature environments. The LM124N also features an integrated protection diode that protects the amplifier from outside interference or interference. Additionally, the amplifier has a high input impedance and low output impedance, making it suitable for use in high impedance circuits.

Conclusion
