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 Operating and storage temperature ranges (Topr,Tstg) 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. 1.5 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) Indicates 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 voltage drift (△Vio/△T) Denotes the ratio of the input offset voltage fluctuation to the ambient temperature fluctuation. 2.3 Input offset current (Iio) Indicates the difference of input bias current between the non-inverting and inverting terminals. 2.4 Input offset current drift (△Iio/△T) Signifies the ratio of the input offset current fluctuation to the ambient temperature fluctuation. 2.5 Input bias current (Ib) Indicates 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. 2.6 Circuit current (ICC) Indicates the current of the IC itself that flows under specified conditions and during no-load steady state. 2.7 High level output voltage/low level output voltage (VOH/VOL) 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. High-level output voltage indicates the upper limit of output voltage. Low-level output voltage indicates the lower limit. 2.8 Large signal voltage gain (AV) Indicates the amplifying rate (gain) of output voltage against the voltage difference between non-inverting terminal and inverting terminal. It is normally the amplifying rate (gain) with reference to DC voltage. Av = (Output voltage fluctuation) / (Input offset fluctuation) 2.9 Input common-mode voltage range (Vicm) Indicates the input voltage range under which the IC operates normally. |
