(note 2) mounted on a fr4 gl ass epoxy pcb70mm70mm1.6mm (c opper foil area less than 3%). (note 3) the voltage difference between inverting input and non-inverting input is the differential input voltage. then input terminal voltage is set to more than vss. (note 4) an excessive input current will flow when input voltages of more than vdd+0.6v or less than vss-0.6v are applied. the input current can be set to less than the rated current by adding a limiting resistor. caution: operating the ic over the absolute maximum ratings may damage the ic. the damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. therefore, it is important to consider circuit protection measures, such as ad ding a fuse, in case the ic is operated over the absolute maximum ratings. free datasheet http:///

(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 within 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 c (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 indica tes the upper limit of out put 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 c an be output from the ic under specific output conditions. the output source current indicates the current flowing out from the ic, and the output sink current indica tes the current flowing into the ic. (11) output rise time /output fall time (t r /t f ) indicates the time required for an output voltage step to change from 10% to 90% of its final value. (12) propagation delay time l to h/ propagation delay time h to l (t plh /t phl ) indicates the time to reach 50% of the output voltage after the step voltage is applied at the input pin. free datasheet http:///
