[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 ...

The name "ikman" comes from the Sinhala term "ඉක්මන්" meaning "fast", or "quick". [1] ikman.lk Launched in June 2013 and is owned by Swedish company Saltside Technologies. ikman.lk became the 6th most visited website in Sri Lanka after three months of operation. [2] The site was initially developed by technical teams based in Sweden ...
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.
Schematic symbol for an OTA has inverting (V in-) and noninverting (V in+) inputs, power supply lines (V + and V −), two biasing inputs (I abc and I bias), and a single output current I out. The LM13700 is an integrated circuit (IC) containing two current -controlled operational transconductance amplifiers (OTA), each having differential ...
Referring to the above diagram, if the op-amp is assumed to be ideal, then the voltage at the inverting (-) input is held equal to the voltage at the non-inverting (+) input as a virtual ground. The input voltage passes a current V in / R 1 {\displaystyle V_{\text{in}}/{R_{1}}} through the resistor producing a compensating current flow through ...
