… The main function of this IC is to do mathematical operation in various circuits. It is possible to add some additional connections to enable the results mismatches in the chip to be significantly reduced. They are usually connected to a variable resistance such as a potentiometer. By adjusting the pot we can null any offset error. Bandwidth Pin 2: Inverting input terminal. As to why exactly an op-amp has input offset: the input circuitry isn't perfectly symmetric, in various ways. To adjust for zero offset, ground the input … Transistor Darlington 6. Using an offset null capability it is possible to reduce the level of the offset voltage significantly. These small offsets are caused by a variety of unavoidable issues within the manufacture of the op amp. As such the offset null capability is essential for the operation of these circuits. Using the offset null capability is easy, and often just requires the addition of a single electronic component: a potentiometer to the circuit, although in some instances digital techniques may be also employed.
It is intended for a wide range of analog applications. Large common mode and differential voltage ranges. The high gain and wide range of operating voltage provide superior performance in intergrator, summing amplifier, and general feedback applications.
Pin 4 is negative voltage supply (VCC) Pin 5 is offset null.
