Description of 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.

1. Absolute maximum ratings

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) Expresses the maximum voltage that can be supplied between the positive and negative supply terminals without causing deterioration of the electrical characteristics or destruction of the internal circuitry.

1.2 Differential input voltage (Vid) Indicates the maximum voltage that can be supplied between the non-inverting and inverting terminals without damaging the IC.

1.3 Input common-mode voltage range (Vicm) Signifies the maximum voltage that can be supplied to non-inverting and inverting terminals without causing deterioration of the characteristics or damage to the IC itself. Normal operation is not guaranteed within the common-mode voltage range of the maximum ratings – use within the input common-mode voltage range of the electric characteristics instead.

1.4 Power dissipation (Pd) Indicates the power that can be consumed by a particular mounted board at ambient temperature (25℃). For packaged products, Pd is determined by the maximum junction temperature and the thermal resistance.

2. Electrical characteristics

2.1 Input offset voltage (Vio) 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 0 V.

2.2 Input offset current (Iio) Indicates the difference of input bias current between the non-inverting and inverting terminals.

2.3 Input bias current (Ib) 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.

2.4 Circuit current (ICC) Indicates the current of the IC itself that flows under specified conditions and during no-load steady state.

2.5

maximum output voltage (VOM)

Indicates the voltage range that can be output by the IC under specified load condition. It is typically divided into high-level output voltage and low-level output voltage.

2.6 Large signal voltage gain (AV) The amplifying rate (gain) of the output voltage against the voltage difference between non-inverting and inverting terminals, it is (normally) the amplifying rate (gain) with respect to DC voltage. AV = (output voltage fluctuation) / (input offset fluctuation)

2.7 Input common-mode voltage range (Vicm) Indicates the input voltage range under which the IC operates normally.

2.8 Common-mode rejection ratio (CMRR) Signifies the ratio of fluctuation of the input offset voltage when the in-phase input voltage is changed (DC fluctuation). CMRR = (change in input common-mode voltage) / (input offset fluctuation)

2.9 Power supply rejection ratio (PSRR) Denotes the ratio of fluctuation of the input offset voltage when supply voltage is changed (DC fluctuation). SVR = (change in power supply voltage) / (input offset fluctuation)

2.10 Channel separation (CS) Expresses the amount of fluctuation of the input offset voltage or output voltage with respect to the change in the output voltage of a driven channel.

2.11 Slew rate (SR) Indicates the time fluctuation ratio of the output voltage when an input step signal is supplied.

2.12 Maximum frequency (ft) Indicates a frequency where the voltage gain of Op-Amp is 1.

2.13 Total harmonic distortion + Noise (THD+N) Indicates the fluctuation of input offset voltage or that of output voltage with reference to the change of output voltage of driven channel.

2.14 Input referred noise voltage (Vn) Indicates a noise voltage generated inside the operational amplifier equivalent by ideal voltage source connected in

series with input terminal.
