(note 10 ) the voltage difference between inverting input and non-inverting in put is the differential input voltage. the input pin voltage is set to more than v ss . (note 11 ) 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 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 betwe en the vdd terminal and vss terminal without deterioration or destruction of characteristics of internal circ uit. (2) differential input voltage (v id ) indicates the maximum voltage that can be applied bet ween 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 co mmon-mode voltage range of the maximum ratings does n ot 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 tem perature 25c (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 resi stance of the package. 2. electrical characteristics (1) input offset voltage (v io ) indicates the voltage difference between non-inverting term inal and inverting terminals. it can be translated into the input voltage difference required for setting the output volta ge at 0 v. (2) input offset voltage drift ( ? v io / ? t) denotes the ratio of the input offset voltage fluctuation to the am bient temperature fluctuation. (3) input offset current (i io ) indicates the difference of input bias current between the non-inverting and inverting terminals. (4) 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. (5) supply current (i dd ) indicates the current that flows within the ic under specified n o-load conditions. (6) shutdown current (idd_sd) indicates the current when the circuit is shutdown. (7) maximum output voltage(high) / maximum output voltage(low) (v oh /v ol ) indicates the voltage range of the output under specifie d load condition. it is typically divided into maximum output voltage high and low. maximum output voltage high indic ates the upper limit of output voltage. maximum output voltage low indicates the lower limit. (8) large signal voltage gain (a v ) indicates the amplifying rate (gain) of output voltage a gainst the voltage difference between non-inverting termina l and inverting terminal. it is normally the amplifying rate (gai n) with reference to dc voltage. a v = (output voltage) / (differential input voltage ) (9) input common-mode voltage range (v icm ) indicates the input voltage range where ic normally operates. (10) 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 fluctua tion) (11) power supply rejection ratio (psrr) indicates the ratio of fluctuation of input offset voltage w hen supply voltage is changed. it is normally the fluctuation of dc. psrr = (change of power supply voltage)/(input offset fluctuation) (12) output source current/ output sink current (i source / i sink ) the maximum current that can be output from the ic under speci fic output conditions. the output source current indicates the current flowing out from the ic, and the output sink c urrent indicates the current flowing into the ic. (13) slew rate (sr) indicates the ratio of the change in output voltage with time whe n a step input signal is applied. (14) unity gain frequency (f t ) indicates a frequency where the voltage gain of operational amplifi er is 1. downloaded from: http:///

(16) phase margin () ( m ) indicates the margin of phase from 180 degree phase lag at unity gain frequency. (17) gain margin ( gm ) indicates the difference between 0db and the gain where operatio nal amplifier has 1 80 degree phase delay. (18) input referred noise voltage (v n ) indicates a noise voltage generated inside the operati onal amplifier equivalent by ideal voltage source conn ected in series with input terminal. (19) total harmonic distortion + noise (thd+n) indicates the fluctuation of input offset voltage or that of outp ut voltage with reference to the change of output voltage of driven channel. (20) channel separation (cs) indicates the fluctuation in the output voltage of the driv en channel with reference to the change of output voltage of the channel which is not driven. (21) turn on time from shutdown (ton) indicates the time from applying the voltage to shutdown termi nal until the ic is active. (22) turn on voltage / turn off voltage (vshdn_h/ vshdn_ l) the ic is active if the shutdown terminal is applied more than tur n on voltage (vshdn_h). the ic is shutdown if the shutdown terminal is applied less than tu rn off voltage (vshdn_l). downloaded from: http:///
