1. Absolute maximum ratings
2. Electrical characteristics item
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.
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 (VDD/VSS)
1.2 Differential input voltage (Vid)
1.3 Input common-mode voltage range (Vicm)
1.4 Power dissipation (Pd)
2.1 Input offset voltage (Vio)
2.2 Input offset current (Iio)
2.3 Input bias current (Ib)
2.4 Circuit current (ICC)
2.5 High level output voltage / Low level output voltage(VOH/VOL)
2.6 Large signal voltage gain (AV)
2.7 Input common-mode voltage range (Vicm)
2.8 Common-mode rejection ratio (CMRR)
2.9 Power supply rejection ratio (PSRR)
2.10 Channel separation(CS)
Indicates the maximum voltage that can be applied between the positive power supply terminal and negative power supply
terminalwithout deterioration or destruction of characteristics of internal circuit.
Indicates the maximum voltage that can be applied between non-inverting terminal and inverting terminal without
deterioration and destruction of characteristics of IC.
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.
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 package(maximum
junction temperature)and thermal resistance of the package.
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].
Indicates the difference of input bias current between non-inverting terminal and inverting terminal.
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.
Indicates the IC current that flows under specified conditions and no-load steady status.
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.
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)
Indicates the input voltage range where IC operates normally.
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)
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)
Indicates the fluctuation of input offset voltage or that of output voltage with reference to the change of output voltage of
driven channel.
