Opamps ==>

Absolute Max. Parameters2

Output Parameters:
1. Output Resistance (Zoi)
The resistance seen 'looking into' the op-amp's output.
2. Output Short-Circuit Current (Iosc)
This is the maximum output current that the op-amp can deliver to a load.
3. Output Voltage Swing (Vo max)
Depending on what the load resistance is, this is the maximum 'peak' output voltage that the op-amp can supply without saturation or clipping.

Dynamic Parameters:
1. Open-Loop Voltage Gain (Aol)
The output to input voltage ratio of the op-amp without external feedback.
2. Large-Signal Voltage Gain
This is the ratio of the maximum voltage swing to the charge in the input voltage required to drive the ouput from zero to a specified voltage (e.g. 10 volts).
3. Slew Rate (SR)
The time rate of change of the ouput voltage with the op-amp circuit having a voltage gain of unity (1.0).

Other Parameters:
1. Supply Current
This is the current that the op-amp will draw from the power supply.
2. Common-Mode Rejection Ratio (CMRR)
A measure of the ability of the op-amp' to reject signals that are simultaneously present at both inputs. It is the ratio of the common-mode input voltage to the generated output voltage, usually
expressed in decibels (dB).
3. Channel Seperation
Whenever there is more than one op-amp in a single package, like the 747 op-amp, a certain amount of "crosstalk" will be present. That is, a signal applied to the input of one section of a dual
op-amp will produce a finite output signal in the remaining section, even though there is no input signal applied to the unused section.
