Explanation of operational amplifier parameters

Parameter	Explanation
Max supply voltage	This is the maximum voltage that should be applied to the operational amplifier. As many of them operate on dual supplies this may be given as ± representing the maximum for both the positive and negative supplies.
Power dissipation	This is the maximum power dissipation permissable for the device.
Maximum differential input	This is the maximum difference that may exist between the two inputs, -IN and +IN. It can normally be in either sense so it is stated as ± xxV.
Junction temperature T_J	This is the maximum temperature that the actual IC chip can operate at, expressed in °C. Remember the ambient temperature will be much less than the actual silicon temperature.
Input offset voltage V_OS	This is the small DC voltage difference that must be applied between the two input terminals to make the output voltage zero, even when the input signal is zero.
Input offset current I_OS	This is equal to the difference between the input bias current at the non-inverting terminal (IB+) minus the input bias current at the inverting (IB- ) terminal of the amplifier.

Parameter	Explanation
Input bias current	This is the DC currents flowing into or out of the amplifier's input pins to create a defined operating point during normal operation.
Input resistance	This is the load resistance resulting from the operational amplifier as seen by a preceding stage.
Input voltage range	The op-amp input voltage range, also known as the common-mode voltage range (CMVR), is the range of voltages that can be applied to the op-amp's inputs while maintaining linear and predictable operation.

These are the main operational amplifier parameters that have been included in our list. There are others, but these help quantify the main elements of the performance of the regulator, but are normally deemed to be less important.

• Further details

Frequency compensation is needed to ensure that operational amplifiers maintain their stability. Many early amplifiers required external compensation, but the famous 741 op amp incorporated on baord compensation.

While this is very convenient, it may be better in some circumstances to be able to tailor the compensation toth e circuit so that the optimum performance can be gain.

This is what the LM301 enables, but providing external connections for the addition of the compensation components.

Interestingly the open loop frequency response starts to fall at frequencies around 100Hz or a little more according to the graphs - those like the 741 and many other internally compensated op-amps see their frequency response start to fall at frequencies as low as 1 Hz or so.
