The TL081 JFET-input operational amplifier is designed to offer a wider selection than any previously developed operational amplifier. TL081 is a single package Op-Amp that has been widely used for quite a long time now. This Op-Amp can be used for many general purpose applications like Voltage follower, Buffers, Comparators, Amplifiers, Adders and much more. So if you looking for a plain old Op-Amp just for some basic circuit design then this IC might be the right choice for you.
An Inverting Amplifier Application circuit from the TL081 datasheet is given below. you only need two resistors to use TL081 as an inverting amplifier.
An inverting amplifier takes a positive/negative voltage on the inverting input pin and makes it a negative/positive voltage of the same magnitude. Output at the VOUT pin is feedback to input through the feedback resistor (Rf).
The input and output voltages can be calculated as: Vin = I.R1Vout = -I.Rf
