Please consider the power dissipation when selecting the output current.
When the output terminal is continuously shorted the output current reduces the internal temperature by flushing.

Datasheet
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, symbol and their meaning may differ from those on other manufacturer’s document or general
documents.
1. Absolute maximum ratings
Absolute maximum rating items indicate 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 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 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 the 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 the IC when mounted on a specific board at ambient temperature 25°C(normal
temperature). As for packaged product, Pd is determined by the temperature that can be permitted by the IC in the
package (maximum junction temperature) and the 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 to 0 V.
2.2 Input offset current (Iio)
Indicates the difference of input bias current between non-inverting terminal and inverting terminal.
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 currents at
the non-inverting and inverting terminals.
2.4 Supply current (ICC)
Indicates the current that flows within the IC under specified no-load conditions.
2.5 Large signal voltage gain (Av)
Indicates the amplification rate (gain) of output voltage against the voltage difference between non-inverting terminal
and inverting terminal. It is normally the amplification rate (gain) with reference to DC voltage.
Av = (Output voltage fluctuation) / (Input offset fluctuation)
2.6 Output saturation voltage (VOM)
Signifies the voltage range that can be output under specific output conditions.
2.7 Input common-mode voltage range (Vicm)
Indicates the input voltage range where IC operates normally.
2.8 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 fluctuation)
2.9 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)
2.10 Slew rate (SR)
Indicates the ratio of the change in output voltage with time when a step input signal is applied.
2.11 Unity Gain Frequency (f
T
)
Indicates a frequency where the voltage gain of Op-Amp is 1.
2.12 Gain Bandwidth (GBW)
The product of the open-loop voltage gain and the frequency at which the voltage gain decreases 6dB/octave.
2.13 Phase Margin (θ)
Indicates the margin of phase from 180 degree phase lag at unity gain frequency.
2.14 Equivalent input noise voltage (Vn)
Indicates a noise voltage generated inside the operational amplifier reflected back to an ideal voltage source
connected in series with input terminal.
