LM193/LM293/LM393/LM2903
Low Power Low Offset Voltage Dual Comparators
General Description
Advantages
n High precision comparators
The LM193 series consists of two independent precision
voltage comparators with an offset voltage specification as
low as 2.0 mV max for two comparators which were de-
signed specifically to operate from a single power supply
over a wide range of voltages. Operation from split power
supplies is also possible and the low power supply current
drain is independent of the magnitude of the power supply
voltage. These comparators also have a unique characteris-
tic in that the input common-mode voltage range includes
ground, even though operated from a single power supply
voltage.
n Reduced VOS drift over temperature
n Eliminates need for dual supplies
n Allows sensing near ground
n Compatible with all forms of logic
n Power drain suitable for battery operation
Features
n Wide supply
— Voltage range:
2.0V to 36V
— Single or dual supplies:
n Very low supply current drain (0.4 mA) — independent
of supply voltage
n Low input biasing current:
n Low input offset current:
n Maximum offset voltage:
n Input common-mode voltage range includes ground
n Differential input voltage range equal to the power
supply voltage
1.0V to 18V
Application areas include limit comparators, simple analog to
digital converters; pulse, squarewave and time delay gen-
erators; wide range VCO; MOS clock timers; multivibrators
and high voltage digital logic gates. The LM193 series was
designed to directly interface with TTL and CMOS. When
operated from both plus and minus power supplies, the
LM193 series will directly interface with MOS logic where
their low power drain is a distinct advantage over standard
comparators.

Note 1: For operating at high temperatures, the LM393 and LM2903 must be derated based on a 125˚C maximum junction temperature and a thermal resistance
of 170˚C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient. The LM193/LM193A/LM293 must be derated based on
a 150˚C maximum junction temperature. The low bias dissipation and the “ON-OFF” characteristic of the outputs keeps the chip dissipation very small (P ≤100 mW),
D
provided the output transistors are allowed to saturate.
+
Note 2: Short circuits from the output to V can cause excessive heating and eventual destruction. When considering short circuits to ground, the maximum output
+
current is approximately 20 mA independent of the magnitude of V .
Note 3: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP
transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action

+
on the IC chip. This transistor action can cause the output voltages of the comparators to go to the V voltage level (or to ground for a large overdrive) for the time
duration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative, again returns
to a value greater than −0.3V.
Note 4: These specifications are limited to −55˚C≤T ≤+125˚C, for the LM193/LM193A. With the LM293 all temperature specifications are limited to
A
−25˚C≤T ≤+85˚C and the LM393 temperature specifications are limited to 0˚C≤T ≤+70˚C. The LM2903 is limited to −40˚C≤T ≤+85˚C.
A
A
A
Note 5: The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output so
no loading change exists on the reference or input lines.
Note 6: The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode
+
+
voltage range is V −1.5V at 25˚C, but either or both inputs can go to 36V without damage, independent of the magnitude of V .
Note 7: The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be obtained, see typical performance
characteristics section.
Note 8: Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the
comparator will provide a proper output state. The low input voltage state must not be less than −0.3V (or 0.3V below the magnitude of the negative power supply,
if used).

Note 9: At output switch point, V .1.4V, R =0Ω with V from 5V to 30V; and over the full input common-mode range (0V to V −1.5V), at 25˚C.

Application Hints
The LM193 series are high gain, wide bandwidth devices
which, like most comparators, can easily oscillate if the
output lead is inadvertently allowed to capacitively couple to
the inputs via stray capacitance. This shows up only during
the output voltage transition intervals as the comparator
change states. Power supply bypassing is not required to
solve this problem. Standard PC board layout is helpful as it
reduces stray input-output coupling. Reducing the input re-
The differential input voltage may be larger than V+ without
damaging the device (Note 8). Protection should be provided
to prevent the input voltages from going negative more than
−0.3 VDC (at 25˚C). An input clamp diode can be used as
shown in the applications section.
The output of the LM193 series is the uncommitted collector
of a grounded-emitter NPN output transistor. Many collectors
can be tied together to provide an output OR’ing function. An
output pull-up resistor can be connected to any available
power supply voltage within the permitted supply voltage
range and there is no restriction on this voltage due to the
magnitude of the voltage which is applied to the V+ terminal
of the LM193 package. The output can also be used as a
simple SPST switch to ground (when a pull-up resistor is not
used). The amount of current which the output device can
sink is limited by the drive available (which is independent of
V+) and the β of this device. When the maximum current limit
is reached (approximately 16mA), the output transistor will
come out of saturation and the output voltage will rise very
rapidly. The output saturation voltage is limited by the ap-
proximately 60Ω rSAT of the output transistor. The low offset
voltage of the output transistor (1.0mV) allows the output to
clamp essentially to ground level for small load currents.
<
sistors to
10 kΩ reduces the feedback signal levels and
finally, adding even a small amount (1.0 to 10 mV) of positive
feedback (hysteresis) causes such a rapid transition that
oscillations due to stray feedback are not possible. Simply
socketing the IC and attaching resistors to the pins will cause
input-output oscillations during the small transition intervals
unless hysteresis is used. If the input signal is a pulse
waveform, with relatively fast rise and fall times, hysteresis is
not required.
All input pins of any unused comparators should be tied to
the negative supply.
The bias network of the LM193 series establishes a drain
current which is independent of the magnitude of the power
supply voltage over the range of from 2.0 VDC to 30 VDC
.
It is usually unnecessary to use a bypass capacitor across
the power supply line.
