Note: 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.
(Note 1) To use at temperature above TA=25°C reduce 5.4mW.
(Note 2) To use at temperature above TA=25°C reduce 5.0mW.
(Note 3) To use at temperature above TA=25°C reduce 4.7mW.
(Note 4) To use at temperature above TA=25°C reduce 8.2mW.
(Note 5) To use at temperature above TA=25°C reduce 6.8mW.
(Note 6) Mounted on a FR4 glass epoxy PCB 70mm×70mm×1.6mm(Copper foil area less than 3%).
(Note 7) The voltage difference between inverting input and non-inverting input is the differential input voltage.
The input terminal voltage is set to more than Vcc-.
(Note 8) An excessive input current will flow when input voltages of less than Vcc--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.

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) Supply Voltage (Vcc+/ Vcc-)
Indicates the maximum voltage that can be applied between the positive power supply pin and negative power
supply pin 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 pins 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 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) Operating and storage temperature ranges (Topr, Tstg)
The operating temperature range indicates the temperature range within which the IC can operate. The higher the
ambient temperature, the lower the power consumption of the IC. The storage temperature range denotes the range
of temperatures the IC can be stored under without causing excessive deterioration of the electrical characteristics.
(5) 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 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 pin and inverting pins. 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 pins.
(3) Input Bias Current (IB)
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) Large Signal Voltage Gain (AV)
Indicates the amplifying rate (gain) of output voltage against the voltage difference between non-inverting pin and
inverting pin. It is normally the amplifying rate (gain) with reference to DC voltage.
AV = (Output Voltage) / (Differential Input Voltage)
(5) Supply Current (ICC)
Indicates the current that flows within the IC under specified no-load conditions.
(6) Input Common-mode Voltage Range (VICM)
Indicates the input voltage range where IC normally operates.
(7) Output Saturation Voltage, Low Level Output Voltage (VOL)
Signifies the voltage range that can be output under specific output conditions.
(8) Output Leakage Current, High Level Output Current (ILEAK)
Indicates the current that flows into the IC under specific input and output conditions.
(9) Output Sink Current (ISINK)
Denotes the maximum current that can be output from the IC under specific output conditions.
(10) Response Time (tRE)
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.

Power Dissipation
Power dissipation (total loss) indicates the power that the IC can consume at TA=25°C (normal temperature). As the IC
consumes power, it heats up, causing its temperature to be higher than the ambient temperature. The allowable
temperature that the IC can accept is limited. This depends on the circuit configuration, manufacturing process, and
consumable power.
Power dissipation is determined by the allowable temperature within the IC (maximum junction temperature) and the
thermal resistance of the package used (heat dissipation capability). Maximum junction temperature is typically equal to the
maximum storage temperature. The heat generated through the consumption of power by the IC radiates from the mold
resin or lead frame of the package. Thermal resistance, represented by the symbol θJA°C/W, indicates this heat dissipation
capability. Similarly, the temperature of an IC inside its package can be estimated by thermal resistance.
Figure 51(a) shows the model of the thermal resistance of a package. The equation below shows how to compute for the
Thermal resistance (θJA), given the ambient temperature (TA), maximum junction temperature (TJmax), and power dissipation
(PD).
θJA = (TJmax－TA) / PD °C/W
The Derating curve in Figure 51(b) indicates the power that the IC can consume with reference to ambient temperature.
Power consumption of the IC begins to attenuate at certain temperatures. This gradient is determined by Thermal
resistance (θJA), which depends on the chip size, power consumption, package, ambient temperature, package condition,
wind velocity, etc. This may also vary even when the same package is used. Thermal reduction curve indicates a reference
value measured at a specified condition. Figure 51(c) and (d) shows an example of the derating curve for LM393xxx,
LM2903xx, LM339xx, and LM2901xx.

Operational Notes
1. Reverse Connection of Power Supply
Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when
connecting the power supply, such as mounting an external diode between the power supply and the IC’s power supply
pins.
2. Pow er Supply Lines
Design the PCB layout pattern to provide low impedance ground and supply lines. Separate the ground and supply
lines of the digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting
the analog block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of
temperature and aging on the capacitance value when using electrolytic capacitors.
3. Ground Voltage
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.
4. Ground Wiring Pattern
When using both small-signal and large-current ground traces, the two ground traces should be routed separately but
connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal
ground caused by large currents. Also ensure that the ground traces of external components do not cause variations
on the ground voltage. The power supply and ground lines must be as short and thick as possible to reduce line
impedance.
5. Thermal Consideration
Should by any chance the power dissipation rating be exceeded, the rise in temperature of the chip may result in
deterioration of the properties of the chip. The absolute maximum rating of the PD stated in this specification is when
the IC is mounted on a 70mm x 70mm x 1.6mm glass epoxy board. In case of exceeding this absolute maximum rating,
increase the board size and copper area to prevent exceeding the PD rating.
6. Recommended Operating Conditions
These conditions represent a range within which the expected characteristics of the IC can be approximately obtained.
The electrical characteristics are guaranteed under the conditions of each parameter.
7. Inrush Current
When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow
instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply.
Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing
of connections.
8. Operation Under Strong Electromagnetic Field
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.
9. Testing on Application Boards
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject
the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should
always be turned off completely before connecting or removing it from the test setup during the inspection process. To
prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and
storage.
10. Inter-pin Short and Mounting Errors
Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in
damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin.
Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and
unintentional solder bridge deposited in between pins during assembly to name a few.

Operational Notes – continued
11. Regarding Input Pins of the IC
This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them
isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a
parasitic diode or transistor. For example (refer to figure below):
When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.
When GND > Pin B, the P-N junction operates as a parasitic transistor.
Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual
interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to
operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should be
avoided.

12. Unused Circuits
When there are unused circuits it is recommended that they be connected as in Figure 53, setting the non-inverting
input pin to a potential within the in-phase input voltage range (VICM).
Figure 53. Disable Circuit Example
13. Input Voltage
Applying Vcc- + 36V to the input pin is possible without causing deterioration of the electrical characteristics or
destruction, regardless of the supply voltage. However, this does not ensure normal circuit operation. Please note that
the circuit operates normally only when the input voltage is within the common-mode input voltage range of the electric
characteristics.
14. Power Supply (single/dual)
The comparator operates when the specified voltage supplied is between Vcc+ and Vcc-. Therefore, the single supply
comparator can be used as a dual supply comparator as well.
15. Terminal short-circuits
When the output and Vcc+ pins are shorted, excessive output current may flow, resulting in undue heat generation and,
subsequently, destruction.
16. IC Handling
Applying mechanical stress to the IC by deflecting or bending the board may cause fluctuations in the electrical
characteristics due to piezo resistance effects.
