The TL071CN is a high-speed JFET input operational amplifier that is an important part of many electronic systems. This operational amplifier stands out because it combines high-voltage JFETs and bipolar transistors that work well together into a single integrated circuit. The TL071CN is a very good worker because it has a low input bias, a high slew rate, a high offset current, and a low offset voltage temperature coefficient. Because of these things, it is a great choice for applications that need precision, speed, and low noise.

TL071CN Features and Benefits

The TL071CN operational amplifier has several key features and benefits that make it a useful and flexible part for electronic circuits:

  • High-Speed Performance: The TL071CN has a high slew rate, which lets it amplify signals that change quickly and correctly with little distortion. Its quick reaction makes it good for applications that need to process signals quickly and accurately.
  • Low Input Bias and Offset Currents: The TL071CN has low input bias and offset currents, which means that the input current has less of an effect on how well the circuit works. This trait is especially important in situations where the accuracy and integrity of the signal are very important.
  • Stability at Different Temperatures: The offset voltage of the TL071CN is very stable at different temperatures. This means that its output stays the same over a wide range of temperatures, making it reliable and predictable even when the world changes.
  • Versatility: The TL071CN is very flexible because it works at high speed, has low input bias and offset currents, and is stable at different temperatures. It can be used for things like amplifying sound, making active filters, adjusting signals, making instruments, and more.
  • The TL071CN has a low offset voltage temperature coefficient; therefore, it can withstand wide temperature swings without significantly altering its output offset voltage. This feature aids in ensuring the reliability and precision of the amplified data.

The TL071CN’s many useful properties—including its rapid speed, low input bias and offset currents, stable temperature, and low offset voltage temperature coefficient—make it a versatile component with many potential applications. Because of its adaptability, reliability, and precision, it is a crucial component in the design of computer circuits.

Electrical Characteristics

The literature says that the TL071CN operational amplifier has the following important electrical properties:

  • Input Voltage Range: The TL071CN can handle both positive and negative input signals well because the suggested input voltage range is from -15V to +15V.
  • Output Voltage Range: When the TL071CN is running on a 15V source, the output voltage range is usually between -13V and +13V.
  • Supply Voltage Requirements: The TL071CN works with a dual supply voltage range of 4V to 18V. This gives you the freedom to choose your power source and fits a wide range of circuit needs.
  • Current Consumption: The TL071CN has a low quiescent current consumption of about 1.4 mA, which makes it a good choice for applications that have limited power and need to use as little power as possible.

These electrical features make sure that the TL071CN works within the voltage ranges stated and uses a reasonable amount of power. They make it possible for the operational amplifier to work successfully in different circuit setups and voltage supply conditions. It’s important to check the datasheet for the TL071CN’s full list of electrical characteristics, including the minimum and maximum values, so that you can use it correctly and fit it into your plan.

Application Circuit Design Considerations

When building an application circuit with the TL071CN operational amplifier, there are a few important things to keep in mind to make sure it works well and that noise and interference are kept to a minimum. Here are some important things to remember:

  • Capacitors that don’t connect: Put decoupling capacitors, which are usually ceramic capacitors, near the V+ and V-power source pins of the TL071CN. These capacitors help cut down on noise and keep the power source stable by storing charge locally for sudden changes in the amount of current needed.
  • Signal Conditioning: Depending on the application, you may need to add parts like resistors, capacitors, and feedback networks to condition the signal. These parts help shape and change the input and output signals to meet the needs of the circuit and get the gain, filtering, or impedance matching that is needed.
  • PCB planning: Follow the rules for PCB planning to reduce noise and interference. Keep the wires that carry sensitive data away from components and power lines that make a lot of noise or have high frequencies. Follow proper grounding methods, such as a dedicated ground plane and proper star grounding, to reduce ground loops and improve signal integrity.
  • Component Placement: Put the TL071CN close to the circuit elements with which it communicates to reduce the length of the wires and the risk of signal loss or noise pickup. Pay attention to how the IC is positioned to make sure the pins connect correctly and to avoid problems with reverse polarity.
  • Power source: Give the TL071CN a clean, stable power source. Avoid sharing power supply lines with noisy components, and if you want to reduce voltage fluctuations and ripple, you might want to use specialized power supply regulators or filters.

By keeping these things in mind and following the suggested guidelines, you can use the TL071CN operational amplifier in your application circuit to get the best performance with the least amount of noise and interference.


In conclusion, the TL071CN operational amplifier stands out as a high-performance option that can be used in a wide range of situations. It has a lot of great features, such as high speed operation, low input bias and offset currents, and stable temperature, which make sure that signals are amplified correctly. The fact that it uses both JFETs and bipolar transistors makes it even more reliable.
