Mounted on an FR4 glass epoxy PCB 70mm×70mm×1.6mm (Copper foil area less than 3%).
Differential Input Voltage is the voltage difference between the inverting and non-inverting inputs. The input pin voltage is set to more than V
EE
.
An excessive input current will flow when input voltages of less than V
EE
-0.6V are applied.
The input current can be set to less than the rated current by adding a limiting resistor.
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.

Consider the power dissipation of the IC under high temperature when selecting the output current value.
There may be a case where the output current value is reduced due to the rise in IC temperature caused by the heat generated inside the IC.

Datasheet
Description of Electrical Characteristics
The relevant electrical terms used in this datasheet are described below. Items and symbols used are also shown. Note
that item names, symbols, and their meanings may differ from those of 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 the
absolute maximum rating or use out of absolute maximum rated temperature environment may cause deterioration of
electrical characteristics.
(1) Supply Voltage (V
CC
/V
EE
)
Indicates the maximum voltage that can be applied between the VCC pin and VEE pin without deterioration of
characteristics of internal circuit.
(2) Differential Input Voltage (V
ID
)
Indicates the maximum voltage that can be applied between the non-inverting and inverting pins without damaging
the IC.
(3) Input Common-mode Voltage Range (V
ICM
)
Indicates the maximum voltage that can be applied to the non-inverting and inverting pins 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 (P
D
)
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, P
D
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 (V
IO
)
Indicates the voltage difference between non-inverting pin and inverting pin. It can be translated to the input voltage
difference required for setting the output voltage to 0V.
(2) Input Offset Current (I
IO
)
Indicates the difference of input bias current between the non-inverting and inverting pins.
(3) Input Bias Current (I
B
)
Indicates the current that flows into or out of the input pin. It is defined by the average of input bias currents at the
non-inverting and inverting pins.
(4) Input Common-mode Voltage Range (V
ICM
)
Indicates the input voltage range at which IC normally operates.
(5) Large Signal Voltage Gain (A
V
)
Indicates the amplification rate (gain) of output voltage against the voltage difference between non-inverting pin and
inverting pin. It is normally the amplification rate (gain) with reference to DC voltage.
Av = (Output Voltage) / (Differential Input Voltage)
(6) Supply Current (I
CC
)
Indicates the current that flows within the IC under specified no-load conditions.
(7) Output Sink Current (I
SINK
)
The maximum current that the IC can output under specific output conditions
(8) Output Saturation Voltage, Low Level Output Voltage (V
OL
)
Signifies the voltage range that can be output under specific output conditions.
(9) Output Leakage Current, High Level Output Current (I
LEAK
)
Indicates the current that flows into the IC under specific input and output conditions.
(10) Response Time (t
RE
)
Response time indicates the delay time between the input and output signal which is determined by the time
difference from the fifty percent of input signal swing to the fifty percent of output signal swing.
