In this article, we will discuss the application fields and working principle of the LT2179IS#TRPBF.

Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

The LT2179IS#TRPBF, provided by Linear Technology, is an operational amplifier designed for use with very high-precision instruments. Its features make it optimized for use in measurements and instrumentation, where accuracy and range are very important. Specifically, it can be used to measure and amplify signals from a wide range of sensitive sensors, including thermocouples and capacitive force transducers. It can also be used as a component in medical instruments, such as MRI machines. In addition, the LT2179IS#TRPBF also has several features that make it well suited for digital-to-analog and analog-to-digital conversions.

The LT2179IS#TRPBF’s application fields are limited by its specs. For instance, it can be used to measure signals up to ±20V while its input bias current is in the range of -400nA to +100nA, with a noise level of 13nV/√Hz. This makes it suitable for measuring inputs that are difficult to accurately interpret. Additionally, it can also be used to amplify signals, as its voltage gain is high enough to allow for precision measurements.

The LT2179IS#TRPBF has a number of features that make it ideal for use in instrumentation and measurement applications. For one thing, its internal design is overbuilt, resulting in higher precision than many other designs. Additionally, it features high noise rejection and excellent stability over a wide range of temperatures. Finally, it is also capable of running on a low-power supply, making it a good choice for battery-powered devices.

Working Principle

The LT2179IS#TRPBF is an operational amplifier with a traditional two-transistor structure. It consists of two independent amplifier stages, where each amplifier has its own set of transistors. The first stage provides the power amplification and the second stage is the voltage-gain stage.

When a signal is applied to one of the input pins of the LT2179IS#TRPBF, it is first received at the first transistor in the amplifier. This signal undergoes power amplification due to the characteristics of the transistor. Once the signal passes through the first stage, it is then passed to the second stage. Here, the signal undergoes voltage gain, which is determined by the resistor net and gain settings.

The LT2179IS#TRPBF also has a differential output stage, which allows it to provide high level of performance and accuracy. This is done by adding a feedback loop between the first and second stages of the amplifier. This feedback loop reduces the amount of noise, popularly known as the Common-Mode-Noise, and ensures the amplifier outputs signals accurately.

In addition, the LT2179IS#TRPBF also features a thermal protection circuit which actively monitors the temperature inside the system. If the temperature exceeds a predetermined level, the circuit will shut down the amplifier to prevent any potential damage. The temperature sensing circuit is also adjustable, making it possible to tailor the circuit’s behavior to the particular application.

Overall, the LT2179IS#TRPBF is designed for use with high precision instruments. Its features make it suitable for use in instrumentation and measurement applications, such as thermocouple readings, capacitive force transducers, medical instruments, and digital-to-analog and analog-to-digital conversions. The LT2179IS#TRPBF’s working principle involves two independent stages and a differential output stage, and it also features a temperature monitoring circuit for added safety.
