Ͷ Description of electrical characteristics
Described here are the terms of electric characteristics used in this technical note. Items and symbols used are also shown.
Note that item name and symbol and their meaning may differ from those on another manufacture’s document or general document.
1. Absolute maximum ratings
Absolute maximum rating item indicates the condition which must not be exceeded. Application of voltage in excess of absolute
maximum rating or use out of absolute maximum rated temperature environment may cause deterioration of characteristics.
1.1 !Power supply voltage VCCVEE
Indicates the maximum voltage that can be applied between the positive power supply terminal and negative power supply terminal
without deterioration or destruction of characteristics of internal circuit.
1.2 !Differential input voltage Vid
Indicates the maximum voltage that can be applied between non-inverting terminal and inverting terminal without deterioration and
destruction of characteristics of IC.
1.3 !Input common-mode voltage range Vicm
Indicates the maximum voltage that can be applied to non-inverting terminal and inverting terminal without deterioration or destruction of
characteristics. Input common-mode voltage range of the maximum ratings not assure normal operation of IC. When normal
Operation of IC is desired, the input common-mode voltage of characteristics item must be followed.
1.4 !Operating temperature range and storage temperature range Topr, Tstg
Operating temperature range indicates the temperature range where IC can operate. The higher the ambient temperature becomes, the
lower is the power consumed by IC. Storage temperature range where IC can be stored without excessive deterioration of characteristics
of IC.
1.5 !Power dissipation Pd
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 packagemaximum junction temperature
and thermal resistance of the package
2. Electrical characteristics item
2.1! Input offset voltage Vio
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]
2.2! Input offset voltage drift Vio/T
Indicates the ratio of input offset voltage fluctuation against ambient temperature fluctuation.
2.3 !Input offset current Iio
Indicates the difference of input bias current between non-inverting terminal and inverting terminal.
2.4! Input offset current drift Iio/T
Indicates the difference of input bias current between non-inverting terminal and inverting terminal.
2.5 !Input bias current Ib
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.
2.6 !Circuit current ICC
Indicates the IC current that flows under specified conditions and no-load steady status.
2.7 !High level output voltage / Low level output voltageVOH/VOL
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.
2.8 !Large signal voltage gain AV
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)
2.9 Input common-mode voltage range Vicm
Indicates the input voltage range where IC operates normally.
2.10 Common-mode rejection ratio CMRR
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
2.11 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.
PSRRChange of power supply voltage/Input offset fluctuation
2.12 Output source current / Output sink current IOH/IOL
Indicates the maximum current that can be output under specified output condition (such as output voltage and load condition). It is
divided into output source current and output sink current. Output source current indicates the current flowing out of IC, and output sink
current flowing into IC.
2.13 Channel separationCS
Indicates the fluctuation of input offset voltage or that of output voltage with reference to the change of output voltage of driven channel.
2.14 Slew rate SR
Indicates the time fluctuation ratio of voltage output when step input signal is applied
2.15 Gain band width product GBW
Indicates the product of specified signal frequency and the gain of Op Amp at such frequency. it gives the approximate value of
frequency where the gain of Op Amp is 1(maximum frequency, and unity gain frequency).
