1. Absolute maximum ratings
2. Electrical characteristics
Described below are descriptions of the relevant electrical terms.
Please note that item names, symbols, and their meanings may differ from those on another manufacturer’s documents.
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.
1.1 Power supply voltage (VCC/VEE)
1.2 Differential input voltage (Vid)
1.3 Input common-mode voltage range (Vicm)
1.4 Power dissipation (Pd)
2.1 Input offset voltage (Vio)
2.2 Input offset current (Iio)
2.3 Input bias current (Ib)
2.4 Input common-mode voltage range (Vicm)
2.5 Large signal voltage gain (AV)
2.6 Circuit current (ICC)
2.7 Output sink current (IOL)
2.8 Output saturation voltage low level output voltage (VOL)
2.9 Output leakage current (ILeak)
2.10 Response time (tre)
2.11 Common-mode rejection ratio (CMRR)
2.12 Power supply rejection ratio (PSRR)
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.
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)
