This is commonly referred to infinite short circuit protection, since the amplifier can drive that value of current into the short circuit indefinitely. The output current that can be expected to be delivered by the op amp is the output current. Typically the limit is set so that the op amp...
If an op amp has protection diodes it will typically have a spec for maximum differential input current. The protection circuit should also show up on the simplified schematic. Some op amps also have back-to-back diodes across the inputs. These are not for input over- voltage protection, ...
The measurement transistor measures the current through the measurement resistance to control a polarisation source in the differential input stage. The polarisation source resistance is selected so the measurement transistor does not easily saturate if a short circuit occurs between the supply terminal ...
Because the output of the op amp must supply currents to two zener circuits and the C1 timing circuit, we will limit the zener currents to no more than 20 percent of the short-circuit output current. That is, (4.32)IZ=0.2IOS In our present case, IZ=0.2×20 mA=4 mA If we use...
Below supply voltage of 6 V, output short circuit condition can be tolerated indefinitely. With the Op Amp tied to a load, the device power dissipation consists of the quiescent power due to the supply current flow into the device, in addition to power dissipation due to the load current. ...

Prior to the 1960s, op amps were very expensive precision circuits costing hundreds of dollars. In 1964, the first op amp was fabricated on an integrated circuit chip. Since that time, the integrated circuit op amp has evolved into a high-performance amplifier costing only a few cents. ...
I have the following circuit on a bread board (with the exception of using AD820 instead of AD822 - the main difference based on the datasheets seemed to be one versus two op amps in one package). simulate this circuit –Schematic created using CircuitLab Simulating the ab...
