![]() For commercial operational amplifiers, the limit is approximately 1.5 V less than the V CC. For an ideal amplifier, op- or otherwise, the outputs should be exactly an amplified copy of the inputs, without distortion or delay. ![]() It is physically impossible for an operational amplifier to generate voltage greater power supply voltage (V CC). Answer (1 of 2): Because a slower slewing-rate limits how fast the outputs can track the inputs. The effect of voltage supply limits is that amplifiers are able to amplify the signals only within the range of their power supply voltage. The power supply rejection ratio (PSRR) is defined as the ratio of the change in input offset voltage due to the change in supply voltage producing it, keeping. The Physical Limitations of Operational Amplifier −Īn operational amplifier is power by an external DC power supply (+V CC and -V CC), which are symmetric and of the order of ± 10 V to ± 20 V. A practical operational amplifier exhibits some limitations that should be considered in the design of instrument.
