(1) supply voltage (vdd/vss) indicates the maximum voltage that can be applied between the vdd terminal and vss terminal without deterioration or destruction of characteristics of internal circuit. (2) differential input voltage (v id ) indicates the maximum voltage that can be applied betw een non-inverting and inverting terminals without damaging the ic. (3) input common-mode voltage range (v icm ) indicates the maximum voltage that can be applied to the non-inverting and inverting terminals without deterioration or destruction of electrical characteristics. input common-mode voltage range of the maximum ratings does not assure normal operation of ic. for normal operation, use the ic wi thin the input common-mode voltage range characteristics. (4) power dissipation (p d ) indicates the power that can be consumed by the ic when mounted on a specific board at the ambient temperature 25 (normal temperature). as for package product, p d is determined by the temperature that can be permitted by the ic in the package (maximum junction temperature) and the thermal resistance of the package. 2. electrical characteristics (1) input offset voltage (v io ) indicates the voltage difference between non-inverting termi nal and inverting terminals. it can be translated into the input voltage difference required for setting the output voltage at 0 v. (2) input offset current (i io ) indicates the difference of input bias current bet ween the non-inverting and inverting terminals. (3) input bias current (i b ) indicates the current that flows into or out of the input terminal. it is defined by the average of input bias currents at the non-inverting and inverting terminals. (4) supply current (i dd ) indicates the current that flows within the ic under specified no-load conditions. (5) maximum output voltage(high) / maximum output voltage(low) (v oh /v ol ) indicates the voltage range of the outpu t under specified load condition. it is typically divided into maximum output voltage high and low. maximum output voltage high indicate s the upper limit of output voltage. maximum output voltage low indicates the lower limit. (6) large signal voltage gain (a v ) 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) / (differential input voltage) (7) input common-mode voltage range (v icm ) indicates the input voltage range where ic normally operates. (8) common-mode rejection ratio (cmrr) indicates the ratio of fluctuation of input offset voltage when the input common mode voltage is changed. it is normally the fluctuation of dc. cmrr = (change of input common-mode voltage)/(input offset fluctuation) (9) power supply rejection ratio (psrr) indicates the ratio of fluctuation of input offset voltage when supply voltage is changed. it is normally the fluctuation of dc. psrr = (change of power supply volta ge)/(input offset fluctuation) (10) output source current / output sink current (i source /i sink ) the maximum current that can be output under specific output conditions, it is divided into output source current and output sink current. the output source current indicates the current flowing out of the ic, and the output sink current the current flowing into the ic. (11) slew rate (sr) indicates the ratio of the change in output voltage wi th time when a step input signal is applied. (12) gain bandwidth (gbw) the product of the open-loop voltage gai n and the frequency at which the voltage gain decreases 6db/octave.

(14) total harmonic distortion + noise (thd+n) indicates the fluctuation of input offset voltage or that of output vo ltage with reference to the change of output voltage of driven channel. (15) channel separation (cs) indicates the fluctuation in the output vo ltage of the driven channel with reference to the change of output voltage of the channel which is not driven.
