[3] [4] [5] An ideal op-amp would have infinite PSRR, as the device should have no change to the output voltage with any changes to the power supply voltage. The output voltage will depend on the feedback circuit, as is the case of regular input offset voltages.
Power-supply rejection The output of a perfect operational amplifier will be independent of power supply voltage fluctuations. Every real operational amplifier has a finite power supply rejection ratio (PSRR) that reflects how well the op amp can reject noise in its power supply from propagating to the output. With increasing frequency the ...
Power supply imperfections (e.g., power signal ripple, non-zero source impedance) may lead to noticeable deviations from ideal operational amplifier behavior. For example, operational amplifiers have a specified power supply rejection ratio that indicates how well the output can reject signals that appear on the power supply inputs. Power ...
Limited output power — if high power output is desired, an op-amp specifically designed for that purpose must be used. Most op-amps are designed for low-power operation and are typically only able to drive output resistances down to 2 kΩ. Limited output current — the output current must obviously be finite. In practice, most op-amps are ...

A genuine Signetics NE5532N in PDIP package, made in 1990, on a modem board A Texas Instruments SA5532A in SOIC package on an audio distribution amplifier board . The NE5532, also sold as SA5532, SE5532 and NG5532 (commonly called just 5532) is a dual monolithic, bipolar, internally compensated operational amplifier (op amp) for audio applications introduced by Signetics in 1979.
From the book "CMOS analog circuit design" by P.Allen, the PSRR is defined as the product of the ratio of the change in supply voltage to the change in output voltage of the op amp caused by the change in the power supply and the open-loop gain of the op amp.
The LM358 is a low-power dual operational amplifier integrated circuit, originally introduced by National Semiconductor. [1] It uses a single power supply from +3 to +30 volts for V CC (though some variants go higher, such as 36 volts for the LM358B). Input voltage can range from −0.3 volts to V CC.
