3D Model

The TL084CN JFET input Operational Amplifier is from the TL08x JFET-input operational amplifier family designed to offer a wider selection than any previously developed operational amplifier family. Each of these JFET-input operational amplifiers incorporates well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit.

The TL084CN is a Quad Package Operational Amplifier, meaning it has four Op-Amps inside it and each Op-Amp can be used independently.

The main distinguishing feature of the TL084CN Op-Amp is that they incorporate high-voltage JFET and bipolar transistors which helps the transistor to have very high input impedance and low bias current. Also, this Op-Amp has low noise and harmonic distortion making it an ideal choice for audio pre-amplifiers. 

TL084CN is very similar to the LM324, they both have four Op-Amps (Operational Amplifiers) inside them and have the exact same pinouts.  The TL084CN however is not meant for common 5V operation as it requires a minimum of 7V to operate. So Unlike LM324 or other op-amps, if you are using the Op-Amp in single supply mode, make sure you provide a minimum of 7V for the Op-Amp to function normally.

If you are curious to learn about few basic application circuits of this IC then you can read through how LM324 is used since both the ICs share the same applications. TL084CN Op amp is very similar to the LM324 Op-Amp, they both have four Op-Amps inside them and have the exact same pinouts.  The TL084CN however is not meant for common 5V operation as it requires a minimum of 7V to operate.
