Comparators
LM393MX,LM 2903MX,LM339MX,LM2901MX
●Description
The Universal Standard family LM393 / LM339 / LM2903 / LM2901 monolithic ICs integrate two / four independent
comparators on a single chip and feature high gain, low power consumption, and an operating voltage range from 2[V] to
36[V] (single power supply).
●Features
1) Operating temperature range Commercia l Grade
LM339/393 family: 0[℃] to +70[℃]
Extended Industrial Grade
LM2903/2901 family: -40[℃] to +85[℃]
2) Open collector output
3) Single / dual power supply compatible
4) Low supply current
0.8[mA] typ.(LM2901/339 family)
0.4[mA] typ.(LM2903/393 family)
5) Low input-bias current: 25[nA] typ.
16) Low input-offset current: 5[nA] typ.
7) Input common-mode voltage range, including ground
8) Differential input voltage range equal to maximum rated supply voltage
9) Low output saturation voltage
10) TTL,MOS,CMOS compatible output

●Description of electrical characteristics
Described below are descriptions of the relevant electrical terms.
Please note that item names, symbols, and their meanings may differ from those on another manufacturer’s documents.
1. Absolute maximum ratings
The absolute maximum ratings are values that should never be exceeded, since doing so may result in deterioration of
electrical characteristics or damage to the part itself as well as peripheral components.
1.1 Power supply voltage (V+/GND)
Expresses the maximum voltage that c an be supplied between the pos itive and negative power supply terminals without
causing deterioration of the electrical characteristics or destruction of the internal circuitry.
1.2 Differential input voltage (VID)
Indicates the maximum voltage that can be supplied between the non-i nverting and inverting terminals without dam aging
the IC.
1.3 Input common-mode voltage range (VICR)
Signifies the maximum voltage that can be supplie d to non-inverting and i nverting terminals without causing deterior ation
of the electrical characteristics or damage to the IC itself. Normal operation is not guaranteed within the input
common-mode voltage range of the maximum ratings – use within the input common-mode voltage range of the electric
characteristics instead.
1.4 Operating temperature range and storage temperature range (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.
1.5 Power dissipation (Pd)
Indicates the power that can be consumed by a particular mounted board at ambient temperature (25°C). For packaged
products, Pd is determined by maximum junction temperatur e and the thermal resistance.
2. Electrical characteristics
2.1 Input offset voltage (VIO)
Signifies the voltage difference between the non-inverting and inverting terminals. It can be thought of as the input
voltage difference required for setting the output voltage to 0V.
2.2 Input offset current (IIO)
Indicates the difference of the input bias current between the non-inverting and inverting t ermina ls.
2.3 Input bias current (IIB)
Denotes the current that flows into or out of the input terminal, it is defined b y the average of the input bias current at the
non-inverting terminal and the input bias current at the inverting terminal.
2.4 Input common-mode voltage range (VICR)
Indicates the input voltage range under which the IC operates normally.
2.5 Large signal voltage gain (AVD)
The amplifying rate (gain) of the output voltage against the voltage difference between the non-inverting and inverting
terminals, it is (normally) the amplifying rate (gain) with respect to DC voltage.
AVD = (output voltage fluctuation) / (input offset fluctuation)
2.6 Circuit current (ICC)
Indicates the current of the IC itself that flows under specific conditions and during no-load steady state.
2.7 Output sink current (IOL)
Denotes the maximum current that can be o utput under specific output conditions.
2.8 Output saturation voltage low level output voltage (VOL)
Signifies the voltage range that can be output under specific output conditions.
2.9 Output leakage current (ILeak)
Indicates the current that flows into the IC under specific input and output conditions.
2.10 Response time (tre)
The interval between the application of input and output conditions.
2.11 Common-mode rejection ratio (CMRR)
Denotes the ratio of fluctuation of the input offset voltage when the in-phase input voltage is changed ( DC fluctuation).
CMRR = (change of input common-mode voltage) / (input offset fluctuation)
2.12 Power supply rejection ratio (PSRR)
Signifies the ratio of fluctuation of the input offset voltage when the supply voltage is changed (DC fluctu ation).
PSRR = (change in power supply voltage) / (input offset fluctuation)

●Notes for use
1) Unused circuits
When there are unused circuits it is recommend ed that they be connec ted as in Fig. 103,
setting the non-inverting input terminal to a potential within the in-phase input voltage
range (VICR).
2) Input terminal voltage
Applying GND + 36V to the input terminal is possible without causing deterioration of
the electrical characteristics or destruction, irrespective of the supply voltage. However,
this does not ensure normal circuit operation. Please note that the circuit operates
normally only when the in put voltage is within the common mode input vo ltage range of
the electric characteristics.
3) Power supply (singl e / dual)
The op-amp operates when the specified voltage supplied is between V+ and GND. Therefore, the single supply
op-amp can be used as a dual supply op-amp as well.
4) Power dissipation Pd
Using the unit in excess of the rated po wer dissipation may cause d eterior ation in electric al char acteristi cs due to a rise
in chip temperature, including reduced current capability. Therefore, please take into consideration the power
dissipation (Pd) under actual operating conditions an d apply a sufficient margin in thermal design. Refer to the thermal
derating curves for more information.
5) Short-circuit between pins and erroneous mounting
Incorrect mounting may damage the IC. In addition, the presence of foreign particles between the outputs, the output
and the power supply, or the output and GND may result in IC destruction.
6) Terminal short-circuits
When the output and V+ terminals are shorted, excessive output current may flow, resulting in undue heat generation
and, subsequently, destruction.
7) Operation in a strong electro m agnetic field
Operation in a strong electromagnetic field may cause malfunctions.
8) Radiation
This IC is not designed to withstand radiation.
9) IC handing
Applying mechanical stress to the IC by deflecting or bending the board may cause fluctuations in the electrical
characteristics due to piezoelectric (piezo) effects.
10) Board inspection
Connecting a capacitor to a pin with low impedance may stress the IC. Therefore, discharging the capacitor after every
process is recommended. In addition, when attaching and detaching the jig during the inspection phase, ensure that
the power is turned OFF before inspection and removal. Furthermore, please take measures against ESD in the
assembly process as well as during transportation and storage.

[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
3. Our Products are designed and manufactured for use under standard conditions and not under any special or
extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way
responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any
special or extraordinary environments or conditions. If you intend to use our Products under any special or
extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of
product performance, reliability, etc, prior to use, must be necessary:
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents
