(Note 10) Excessive input current will flow if a differential input voltage in excess of approximately 0.6V is applied between the input unless some limiting

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 important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.

Datasheet
Description of electrical characteristics
Described below are descriptions of the relevant electrical terms 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 manufacturer’s document or
general document.
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) 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.
(2) Differential input voltage (VID)
Indicates the maximum voltage that can be applied between non-inverting and inverting terminals without damaging
the IC.
(3) Input common-mode voltage range (VICM)
Indicates the maximum voltage that can be applied to the non-inverting and inverting terminals without deterioration
or destruction of electrical characteristics. Input common-mode voltage range of the maximum ratings does not assure
normal operation of IC. For normal operation, use the IC within the input common-mode voltage range characteristics.
(4) Power dissipation (Pd)
Indicates the power that can be consumed by the IC when mounted on a specific board at the ambient temperature 25°C
(normal temperature). As for package 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
(1) Input offset voltage (VIO)
Indicates the voltage difference between non-inverting terminal and inverting terminals. It can be translated into the
input voltage difference required for setting the output voltage at 0 V.
(2) Input offset current (IIO)
Indicates the difference of input bias current between the non-inverting and inverting terminals.
(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.
(4) Input common-mode voltage range (VICM)
Indicates the input voltage range where IC normally operates.
(5) 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) / (Differential Input voltage)
(6) Supply current (ICC)
Indicates the current that flows within the IC under specified no-load conditions.
(7) Output sink current (ISINK)
Denotes the maximum current that can be output under specific output conditions.
(8) Output saturation voltage, low level output voltage (VOL)
Signifies the voltage range that can be output under specific output conditions.
(9) Output leakage current, High level output current (ILEAK)
Indicates the current that flows into the IC under specific input and output conditions.
(10) Response time (tRE)
Response time indicates the delay time between the input and output signal is determined by the time difference
from the fifty percent of input signal swing to the fifty percent of output signal swing.
