(note 4) mounted on a fr4 glass epoxy pcb 70mm70mm1.6mm (copper foil a rea less than 3%). (note 5) the voltage difference between inverting input and non-inver ting input is the differential input voltage. then input pin voltage is set to more than v ss . (note 6) 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 b etween pins or an open circuit between pins and the internal circuitry. therefore, it is imp ortant to consider circuit protection measures, such as adding a fuse, in case the ic is operated over the absolute maximum ratings. downloaded from: http:///

(1) supply voltage (vdd/vss) indicates the maximum voltage that can be applied betw een 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 between 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 deteriorati on or destruction of electrical characteristics. input common-mode voltage range of the maximum ratings do es not assure normal operation of ic. for normal operation, use t he ic within the input common-mode voltage range ch aracteristics. (4) power dissipation (p d ) indicates the power that can be consumed by the ic when mounted on a specific board at the ambient tem perature 25c (normal temperature). as for package product, pd is dete rmined by the temperature that can be permitted by the ic i n the package (maximum junction temperature) and the thermal resis tance of the package. 2. electrical characteristics (1) input offset voltage (v io ) indicates the voltage difference between non-inverting te rminal and inverting terminals. it can be translated into th e input voltage difference required for setting the output volt age at 0 v. (2) input offset current (i io ) indicates the difference of input bias current between the non-inv erting and inverting terminals. (3) input bias current (i b ) indicates the current that flows into or out of the input termi nal. 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-loa d conditions. (5) maximum output voltage(high) / maximum output voltage(low) (v oh /v ol ) indicates the voltage range of the output under specified load condition. it is typically divided into maximum ou tput voltage h igh and low. maximum output voltage high indicates the uppe r 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 agains t the voltage difference between non-inverting terminal and inverting terminal. it is normally the amplifying rate (gain) w ith reference to dc voltage. a v = (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 r eje ction ratio (cmrr) indicates the ratio of fluctuation of input offset voltage wh en the input common mode voltage is changed. it is normally the fluctuation of dc. cmrr = (change of input common-mode voltage)/(input offset fluctua tion) (9) power supply r ej ection 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 voltage)/(input offset fluctuation) (10) output source current/ output s ink current (i source / i sink ) the maximum current that can be output from the ic under spe cific output conditions. the output source current indicates the current flowing out from the ic, and the output sink curre nt indicates the current flowing into the ic. (11) slew rate (sr) indicates the ratio of the change in output voltage with time when a step input signal is applied. (1 2) gain bandwidth (gbw) the product of the open-loop voltage gain and the frequency at which the voltage gain decreases 6db/octave. (13) phase margin () indicates the margin of phase from 180 degree phase lag at uni ty gain frequency. downloaded from: http:///
