![]() ![]() ![]() By varying the potentiometer, we can vary the input voltage and the output voltage will also vary, to power the op-amp we have used +12V and -12V supply, as the gain of the op-amp is 10 so if we provide 1V at the input we will get 10V at the output and the simulated circuit shows exactly that. For that we have used a 1K resistor and a 9.1K resistor, as you can see for the simulation, we have used a variable potentiometer. In the above the TL082 Op-amp is configured as a non-inverting configuration. As a test, a non-inverting op-amp configuration is shown below. TL082 Op-Amp IC can be used for audio pre-amplification and it can provide an edge in terms of sound quality because of its price compared to its specs. So, if you are looking for an Op-Amp IC with Quad package and JFET driven then this IC might be the right choice for you. These devices also exhibit low noise and offset voltage drift. Other than that, these amplifiers may be used in applications such as high-speed integrators, fast D/A converters, sample and hold circuits and many other circuits requiring low input offset voltage, low input bias current, high input impedance, high slew rate and wide bandwidth. Also, this Op-Amp has low noise and harmonic distortion making it an ideal choice for audio pre-amplifiers. The main distinguishing feature of the TL082 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. The TL082 is a Dual Package Operational Amplifier, meaning it has two Op-Amps inside it and each Op-Amp can be used independently. Note: Complete Technical Details can be found in the TL082 IC datasheet given at the end of this page. Internally Trimmed Offset Voltage: 15 mV.Common mode Rejection Ratio CMRR: 100dB.Typical Operating Voltage: +18V to -18V.Ground or Negative (Dual Polarity Supply) In addition, well-matched high voltage JFET input devices provide very low input bias and offset currents. This device requires a low supply current yet maintains a large gain bandwidth product and fast slew rate. The TL082 Op-Amp is a low cost, high speed, dual JFET input operational amplifier with an internally trimmed input offset voltage. ![]()
