Op-Amp/Comparator Application Note - Rohm
Each op-amp circuit is composed of five terminals: a power supply terminal on the positive side, a power supply terminal on the negative side, a + input terminal, a - input terminal, and an output terminal. (There are no general terms for the terminals except classifications such as power source, input and output.) Table 1.1.1.

www.analog.comPOWER SUPPLY REJECTION RATIO (PSRR) If the supply of an op amp changes, its output should not, but it typically does. If a change of X volts in the supply produces an output voltage change of Y volts, then the PSRR on that supply (referred to the output, RTO) is X/Y. The dimensionless ratio is generally called the power supply rejection ratio ...
