Indicates the power that can be consumed by specified mounted board at the ambient temperature 25℃(normal temperature). As for
package product, Pd is determined by the temperature that can be permitted by IC chip in the package（maximum junction temperature）
and thermal resistance of the package
Indicates the voltage difference between non-inverting terminal and inverting terminal. It can be translated into the input voltage
difference required for setting the output voltage at 0 [V]
Indicates the difference of input bias current between non-inverting terminal and inverting terminal.
Indicates the current that flows into or out of the input terminal. It is defined by the average of input bias current at non-inverting terminal
and input bias current at inverting terminal.
Indicates the IC current that flows under specified conditions and no-load steady status.
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.
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)
Indicates the input voltage range where IC operates normally.
Indicates the ratio of fluctuation of input offset voltage when in-phase input voltage is changed. It is normally the fluctuation of DC.
CMRR ＝（Change of Input common-mode voltage）/（Input offset fluctuation）
Indicates the ratio of fluctuation of input offset voltage when supply voltage is changed. It is normally the fluctuation of DC.
