TL082ACN is a high-performance operational amplifier (op-amp) belonging to the linear amplifier family. It is a dual JFET (junction field effect transistor) input amplifier commonly used in a variety of applications, ranging from instrumentation and test & measurement systems to consumer electronics. It is particularly well suited for use in the frequency domain due to its low noise figures, wide dynamic range and good common mode rejection ratio. This article provides an overview of TL082ACN application field and its general working principle.

Overview of Applications

TL082ACN is an ideal op-amp for instrumentation and test & measurement systems. Due to its low noise figure and good frequency response, it is well suited for a wide range of signal conditioning and data-conversion tasks. It is particularly well suited for semi-conductor wafer testing and defect detection systems, as it is capable of delivering very-high speed operation with high accuracy and resolution. It is also widely used in medical imaging technologies, where its low-noise output and wide dynamic range are invaluable assets.

In addition to instrumentation and medical applications, TL082ACN is often employed in consumer and automotive electronics. Its widely-accepted characteristics, such as high speed and high IP3 (third-order intermodulation), make it suitable for use in a variety of consumer electronics such as radios, cell phones, automotive audio systems, and GPS devices.

Overall, TL082ACN is an ideal op-amp for instrumentation, medical, consumer, and automotive applications due to its high performance characteristics and wide dynamic range.

General Working Principle

TL082ACN is a dual JFET input amplifier. It consists of two totally independent, high gain, internally frequency compensated amplifiers. The input differential resistance of both amplifiers is very high, and each one of them has an offset voltage of 1mV or less, which makes the amplifier virtually free from input-referred offset voltage errors.

The amplifier gains are internally set to 20V/V by the factory. However, they can be adjusted by the addition of an external resistor, allowing for a wide range of gain settings. The TL082ACN can operate from single supply voltages as low as 2.7V or dual supplies from, for example, ±1.35V. The output voltage swings almost rail-to-rail, making the amplifier ideal for use in a wide variety of signal conditioning and data-conversion applications.

For input signal frequency range and high-level output, TL082ACN amplifiers exhibit excellent common-mode rejection (CMR) ratios up to 85dB, at a frequency range up to 10 KHz. This is perfect for signal conditioning applications that require stability and high common-mode rejection. A slew rate of 16V/US makes the TL082ACN suitable for use in applications with pulse signals.

In summary, TL082ACN is a reliable, high-performance operational amplifier. Its dual JFET input architecture, wide dynamic range, good common-mode rejection ratio, high slew rate and low noise figure make it ideal for a variety of analog signal conditioning and data-conversion applications.
