Description of Electrical Characteristics
Described here are the terms of electric characteristics used in this datasheet. 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 (VCC-VEE)
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 supplied between the non-inverting and inverting terminals without
damaging the 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 assures
normal operation of IC. When normal Operation of IC is desired, the input common-mode voltage of characteristics
item must be followed.
1.4 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 package
(maximum junction temperature) and thermal resistance of the package.
2. Electrical characteristics
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 current (Iio)
Indicates the difference of input bias current between the non-inverting and inverting terminals.
2.3 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.
2.4 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)
2.5 Maximum Output Voltage (VOM)
Signifies the voltage range that can be output under specific output conditions.
2.6 Input common-mode voltage range (Vicm)
Indicates the input voltage range under which the IC operates normally.
2.7 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)
2.8 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 voltage)/(Input offset fluctuation)
2.9 Circuit current (ICC)
Indicates the IC current that flows under specified conditions and no-load steady status.
2.10 Output source current/ output sink current (Isource/Isink)
The maximum current that can be output under specific output conditions, it is divided into output source current and
output sink current. The output source current indicates the current flowing out of the IC, and the output sink current
the current flowing into the IC.

2.11 Slew Rate (SR)
SR is a parameter that shows movement speed of operational amplifier. It indicates rate of variable output voltage
as unit time.
2.12 Unity gain frequency (f
T
)
Indicates a frequency where the voltage gain of operational amplifier is 1.
2.13 Total harmonic distortion + Noise (THD+N)
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 Gain Band Width (GBW)
Indicates to multiply by the frequency and the gain where the voltage gain decreases 6dB/octave.
