This is the capacitance between the input terminals with either input grounded. the frequency at which the gain falls to unity. This parameter is the bandwidth for which the open-loop voltage amplification is greater that unity, i.e.

this is the gain for a voltage difference between the inverting and non-inverting inputs. This parameter is the ratio of the change in the output voltage to the change in differential input voltage producing it with the common-mode input voltage held constant. It is the ratio of the peak-to-peak output voltage swing to the change in input voltage required to drive the output for large signals. This parameter is one of the commonly used specifications. This parameter is often seen in datasheets and is the reciprocal of the open-loop voltage amplification at the lowest frequency at which the open-loop phase shift is such that the output is in phase with the inverting input. This specification is absolute value of the open-loop phase shift between the output and the inverting input at the frequency at which the modulus of the open-loop amplification is unity.

Common Op Amp Specifications & Datasheet Parameters The table below provides details of some of the major specifications and parameters encountered in op amp datasheets. Chips designers have to balance cost, and various conflicting areas of performance and therefore it is not possible to provide a single chip that meets every single requirement. Some op amps are ideal for general applications, whereas other op amp chips have been designed to provide particular levels of performance in some areas. Like any electronic component, operational amplifiers have their performance defined in datasheets - these carry a variety of specifications and parameters which define the performance, and from these it should be possible to identify whether any given device will be suitable for a particular application.
