Voltage Comparator
General Description
The LM111 is a voltage comparator that has input currents
nearly a thousand times lower than devices such as the
LM106 or LM710. It is also designed to operate over a wider
range of supply voltages: from standard ±15V op amp sup-
plies down to the single 5V supply used for IC logic. The
output is compatible with RTL, DTL and TTL as well as MOS
circuits. Further, it can drive lamps or relays, switching volt-
ages up to 50V at currents as high as 50 mA.
Both the inputs and the outputs of the LM111 can be isolated
from system ground, and the output can drive loads referred
to ground, the positive supply or the negative supply. Offset
balancing and strobe capability are provided and outputs can
be wire OR'ed. Although slower than the LM106 and LM710
(200 ns response time vs 40 ns) the device is also much less
prone to spurious oscillations. The LM111 has the same pin
configuration as the LM106 and LM710.

Note 2: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 3: This rating applies for ±15V supplies. The positive input voltage limit is 30 V above the negative supply. The negative input voltage limit is equal to the
negative supply voltage or 30V below the positive supply, whichever is less.
Note 4: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), θJA (package
junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax = (TJmax - TA)/
θJA or the number given in the Absolute Maximum Ratings, whichever is lower.

CIRCUIT TECHNIQUES FOR AVOIDING
OSCILLATIONS IN COMPARATOR APPLICATIONS
When a high-speed comparator such as the LM111 is used
with fast input signals and low source impedances, the output
response will normally be fast and stable, assuming that the
power supplies have been bypassed (with 0.1 μF disc capac-
itors), and that the output signal is routed well away from the
inputs (pins 2 and 3) and also away from pins 5 and 6.
However, when the input signal is a voltage ramp or a slow
sine wave, or if the signal source impedance is high (1 kΩ to
100 kΩ), the comparator may burst into oscillation near the
crossing-point. This is due to the high gain and wide band-
width of comparators such as the LM111. To avoid oscillation
or instability in such a usage, several precautions are recom-
mended, as shown in Figure 1 below.
1. The trim pins (pins 5 and 6) act as unwanted auxiliary
inputs. If these pins are not connected to a trim-pot, they
should be shorted together. If they are connected to a
trim-pot, a 0.01 μF capacitor C1 between pins 5 and 6
will minimize the susceptibility to AC coupling. A smaller
capacitor is used if pin 5 is used for positive feedback as
in Figure 1.
2. Certain sources will produce a cleaner comparator
output waveform if a 100 pF to 1000 pF capacitor C2 is
connected directly across the input pins.
3. When the signal source is applied through a resistive
network, RS, it is usually advantageous to choose an RS
′ of substantially the same value, both for DC and for
dynamic (AC) considerations. Carbon, tin-oxide, and
metal-film resistors have all been used successfully in
comparator input circuitry. Inductive wire wound resistors
are not suitable.
4. When comparator circuits use input resistors (e.g.
summing resistors), their value and placement are
particularly important. In all cases the body of the resistor
should be close to the device or socket. In other words
there should be very little lead length or printed-circuit foil
run between comparator and resistor to radiate or pick
up signals. The same applies to capacitors, pots, etc. For
example, if RS=10 kΩ, as little as 5 inches of lead
between the resistors and the input pins can result in
oscillations that are very hard to damp. Twisting these
input leads tightly is the only (second best) alternative to
placing resistors close to the comparator.
5. Since feedback to almost any pin of a comparator can
result in oscillation, the printed-circuit layout should be
engineered thoughtfully. Preferably there should be a
ground plane under the LM111 circuitry, for example, one
side of a double-layer circuit card. Ground foil (or,
positive supply or negative supply foil) should extend
between the output and the inputs, to act as a guard. The
foil connections for the inputs should be as small and
compact as possible, and should be essentially
surrounded by ground foil on all sides, to guard against
11 www.national.com
LM111JAN
capacitive coupling from any high-level signals (such as
the output). If pins 5 and 6 are not used, they should be
shorted together. If they are connected to a trim-pot, the
trim-pot should be located, at most, a few inches away
from the LM111, and the 0.01 μF capacitor should be
installed. If this capacitor cannot be used, a shielding
printed-circuit foil may be advisable between pins 6 and
7. The power supply bypass capacitors should be located
within a couple inches of the LM111. (Some other
comparators require the power-supply bypass to be
located immediately adjacent to the comparator.)
6. It is a standard procedure to use hysteresis (positive
feedback) around a comparator, to prevent oscillation,
and to avoid excessive noise on the output because the
comparator is a good amplifier for its own noise. In the
circuit of Figure 2, the feedback from the output to the
positive input will cause about 3 mV of hysteresis.
However, if RS is larger than 100Ω, such as 50 kΩ, it
would not be reasonable to simply increase the value of
the positive feedback resistor above 510 kΩ. The circuit
of Figure 3 could be used, but it is rather awkward. See
the notes in paragraph 7 below.
7. When both inputs of the LM111 are connected to active
signals, or if a high-impedance signal is driving the
positive input of the LM111 so that positive feedback
would be disruptive, the circuit of Figure 1 is ideal. The
positive feedback is to pin 5 (one of the offset adjustment
pins). It is sufficient to cause 1 to 2 mV hysteresis and
sharp transitions with input triangle waves from a few Hz
to hundreds of kHz. The positive-feedback signal across
the 82Ω resistor swings 240 mV below the positive
supply. This signal is centered around the nominal
voltage at pin 5, so this feedback does not add to the
VOS of the comparator. As much as 8 mV of VOS can be
trimmed out, using the 5 kΩ pot and 3 kΩ resistor as
shown.
8. These application notes apply specifically to the LM111
and LF111 families of comparators, and are applicable
to all high-speed comparators in general, (with the
exception that not all comparators have trim pins).

obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a
