Explanation of operational amplifier parameters

Parameter	Explanation
Max supply voltage	This is the maximum voltage that should be applied toth e 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.

• Further details

The 741 is probably one of the all-time largest produced operationa amplifiers. Initially produced as far back as the 1960s and 70s, it has remained a current active part since then. It provides all the capabilities that are normally required for a basic general purpose operational amplifier.
