The absolute maximum ratings are values that should never be exceeded, since doing so may result in deterioration of electrical
characteristics or damage to the part itself as well as peripheral components.
Expresses the maximum voltage that can be supplied between the positive and negative power supply terminals without causing
deterioration of the electrical characteristics or destruction of the internal circuitry.
Indicates the maximum voltage that can be supplied between the non-inverting and inverting terminals without damaging the IC.
Signifies the maximum voltage that can be supplied to non-inverting and inverting terminals without causing deterioration of the electrical
characteristics or damage to the IC itself. Normal operation is not guaranteed within the input common-mode voltage range of the
maximum ratings – use within the input common-mode voltage range of the electric characteristics instead.
The operating temperature range indicates the temperature range within which the IC can operate. The higher the ambient temperature,
the lower the power consumption of the IC. The storage temperature range denotes the range of temperatures the IC can be stored
under without causing excessive deterioration of the electrical characteristics.
Indicates the power that can be consumed by a particular mounted board at ambient temperature (25°C). For packaged products, Pd is
determined by maximum junction temperature and the thermal resistance.
Signifies the voltage difference between the non-inverting and inverting terminals. It can be thought of as the input voltage difference
required for setting the output voltage to 0V.
Indicates the difference of the input bias current between the non-inverting and inverting terminals.
Denotes the current that flows into or out of the input terminal, it is defined by the average of the input bias current at the non-inverting
terminal and the input bias current at the inverting terminal.
Indicates the input voltage range under which the IC operates normally.
The amplifying rate (gain) of the output voltage against the voltage difference between the non-inverting and inverting terminals, it is
(normally) the amplifying rate (gain) with respect to DC voltage.
AVD = (output voltage fluctuation) / (input offset fluctuation)
Indicates the current of the IC itself that flows under specific conditions and during no-load steady state.
Denotes the maximum current that can be output under specific output conditions.
Signifies the voltage range that can be output under specific output conditions.
Indicates the current that flows into the IC under specific input and output conditions.
The interval between the application of input and output conditions.
Denotes the ratio of fluctuation of the input offset voltage when the in-phase input voltage is changed (DC fluctuation).
CMRR = (change of input common-mode voltage) / (input offset fluctuation)
Signifies the ratio of fluctuation of the input offset voltage when the supply voltage is changed (DC fluctuation).
PSRR = (change in power supply voltage) / (input offset fluctuation)
