APPLICATION INFORMATION
BENEFITS OF THE LMC7221 TINY COMPARATOR
Size
The small footprint of the 5-Pin SOT-23 packaged Tiny Comparator, (0.120 x 0.118 inches, 3.05 x 3.00 mm)
saves space on printed circuit boards, and enable the design of smaller electronic products. Because they are
easier to carry, many customers prefer smaller and lighter products.
Height
The height (0.056 inches, 1.43 mm) of the Tiny Comparator makes it possible to use it in PCMCIA type III cards.
Simplified Board Layout
The Tiny Comparator can simplify board layout in several ways. First, by placing a comparator where
comparators are needed, instead of routing signals to a dual or quad device, long pc traces may be avoided.
By using multiple Tiny Comparators instead of duals or quads, complex signal routing and possibly crosstalk can
be reduced.
Low Supply Current
The typical 7 μA supply current of the LMC7221 extends battery life in portable applications, and may allow the
reduction of the size of batteries in some applications.
Wide Voltage Range
The LMC7221 is characterized at 15V, 5V and 2.7V. Performance data is provided at these popular voltages.
This wide voltage range makes the LMC7221 a good choice for devices where the voltage may vary over the life
of the batteries.
Digital Outputs Representing Signal Level
Comparators provide a high or low digital output depending on the voltage levels of the (+) and (−) inputs. This
makes comparators useful for interfacing analog signals to microprocessors and other digital circuits. The
LMC7221 can be thought of as a one-bit a/d converter.
Open Drain Output
The open drain output is like the open collector output of a logic gate. This makes the LMC7221 very useful for
mixed voltage systems.

Driving LEDs (Light Emitting Diodes)
With a 5 volt power supply, the LMC7221's output sinking current can drive small, high efficiency LEDs for
indicator and test point circuits. The small size of the Tiny package makes it easy to find space to add this
feature to even compact designs.
Input range to Beyond Rail to Rail
The input common mode range of the LMC7221 is slightly larger than the actual power supply range. This wide
input range means that the comparator can be used to sense signals close to the power supply rails. This wide
input range can make design easier by eliminating voltage dividers, amplifiers, and other front end circuits
previously used to match signals to the limited input range of earlier comparators. This is useful to power supply
monitoring circuits which need to sense their own power supply, and compare it to a reference voltage which is
close to the power supply voltage. The wide input range can also be useful for sensing the voltage drop across a
current sense resistor for battery chargers.
Zero Crossing Detector
Since the LMC7221's common mode input range extends below ground even when powered by a single positive
supply, it can be used with large input resistors as a zero crossing detector.
Low Input Currents and High Input Impedance
These characteristics allow the LMC7221 to be used to sense high impedance signals from sensors. They also
make it possible to use the LMC7221 in timing circuits built with large value resistors. This can reduce the power
dissipation of timing circuits. For very long timing circuits, using high value resistors can reduce the size and cost
of large value capacitors for the same R-C time constant.
Direct Sensor Interfacing
The wide input voltage range and high impedance of the LMC7221 may make it possible to directly interface to a
sensor without the use of amplifiers or bias circuits. In circuits with sensors which can produce outputs in the
tens to hundreds of millivolts, the LMC7221 can compare the sensor signal with an appropriately small reference
voltage. This may be done close to ground or the positive supply rail. Direct sensor interfacing may eliminate the
need for an amplifier for the sensor signal. Eliminating the amplifier can save cost, space, and design time.
LOW VOLTAGE OPERATION
Comparators are the common devices by which analog signals interface with digital circuits. The LMC7221 has
been designed to operate at supply voltages of 2.7V without sacrificing performance to meet the demands of 3V
digital systems.
At supply voltages of 2.7V, the common-mode voltage range extends 200 mV (ensured) below the negative
supply. This feature, in addition to the comparator being able to sense signals near the positive rail, is extremely
useful in low voltage applications.
Figure 16. Even at Low-Supply Voltage of 2.7V, an Input Signal which Exceeds the Supply Voltages
Produces No Phase Inversion at the Output
At V+ = 2.7V propagation delays are tPLH = 4 μs and tPHL = 4 μs with overdrives of 100 mV.

OPEN DRAIN OUTPUT
Output Stage
Figure 17. Output Stage
Figure 17 shows the difference between push-pull output and open drain output.
Push pull outputs will have a conventional high or low digital output, the same as a logic gate. Low will be the
negative supply rail (usually ground) and high will be the positive supply rail.
This is useful if the chips you are interfacing to run on the same supply voltage as the comparator. An example
would be an all +5V system.
Open drain outputs will only pull low—for the high output they depend on an external pull-up resistor. This can
pull up to a voltage higher or lower than the comparator supply voltage. This voltage can be as high as 15V. This
makes the open drain parts useful in mixed voltage systems. An example would be where the comparator runs at
5V and the logic circuits are at 3.3V. The pull-up resistor would go to the 3.3V supply.
Open drain outputs are the CMOS equivalent of open collector outputs.
OUTPUT SHORT CIRCUIT CURRENT
The LMC7221 has short circuit protection of 40 mA. However, it is not designed to withstand continuous short
circuits, transient voltage or current spikes, or shorts to any voltage beyond the supplies. A resistor in series with
the output should reduce the effect of shorts. For outputs which send signals off PC boards additional protection
devices, such as diodes to the supply rails, and varistors may be used.
INPUT PROTECTION
If input signals are likely to exceed the common mode range of the LMC7221, or it is likely that signals may be
present when power is off, damage to the LMC7221 may occur. Large value (100 kΩ to MΩ) input resistors may
reduce the likelihood of damage by limiting the input currents. Since the LMC7221 has very low input leakage
currents, the effect on accuracy will be small. Additional protection may require the use of diodes, as shown in
Figure 18. Note that diode leakage current may affect accuracy during normal operation.
The R-C time constant of RIN and the diode capacitance may also slow response time.

LAYOUT CONSIDERATIONS
The LMC7221 is not an especially fast comparator, so high speed design practices are not required. The
LMC7221 is capable of operating with very high impedance inputs, so precautions should be taken to reduce
noise pickup with high impedance (∼ 100 kΩ and greater) designs and in electrically noisy environments.
Keeping high value resistors close to the LMC7221 and minimizing the size of the input nodes is a good practice.
With multilayer designs, try to avoid long loops which could act as inductors (coils). Sensors which are not close
to the comparator may need twisted pair or shielded connections to reduce noise.
PUSH-PULL OUTPUTS, DUAL VERSIONS
The LMC7211 is a comparator similar to the LMC7221, but with push-pull outputs which can source current.
The performance of the LMC7221 is available in a dual device. Please see the LMC6772 datasheet. For a dual
device with push-pull outputs, please see the LMC6762 datasheet.

(2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish
value exceeds the maximum column width.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
