3 Description
The LMC7211-N is a micropower CMOS comparator available in the space saving SOT23-5 package. This makes the comparator designed for space and weight critical designs. The LMC7211-N is supplied in two offset voltage grades, 5mV and 15mV. The main benefits of the tiny package are most apparent in small portable electronic devices, such as mobile phones, pagers, notebook computers, personal digital assistants, and PCMCIA cards. The rail-to-rail input voltage makes the LMC7211-N a good choice for sensor interfacing, such as light detector circuits, optical and magnetic sensors, and alarm and status circuits. The tiny comparator's outside dimensions (length x width x height) of 3.05mm × 3.00mm × 1.43mm allow the device to fit into tight spaces on PC boards. See the LMC7221 for a comparator with an open- drain output. 8-Pin SOIC-8 Top View 5-Pin SOT23-5 Top View LMC7211-N SNOS746G – MAY 2004 – REVISED DECEMBER 2025 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.

5 Application Information
5.1 Benefits of the LMC7211-N Tiny Comparator
saves space on printed circuit boards, and enables the design of smaller electronic products. Because smaller electronics are easier to carry, many customers prefer smaller and lighter products. Height. The height (0.056 inches, 1.43mm) of the tiny comparator makes the use in PCMCIA type III cards possible. 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 can 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 LMC7211-N extends battery life in portable applications, and can allow the reduction of the size of batteries in some applications. Wide Voltage Range. The LMC7211-N is characterized at 15V, 5V and 2.7V. Performance data is provided at these popular voltages. This wide voltage range makes the LMC7211-N a good choice for devices where the voltage can 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 LMC7211-N can be thought of as a one-bit a/d converter. Push-Pull Output. The push-pull output of the LMC7211-N is capable of both sourcing and sinking milliamp level currents even at a 2.7V supply. This can allow the LMC7211-N to drive multiple logic gates. Driving LEDs (Light Emitting Diodes). With a 5V power supply, the LMC7211-N's output sinking current can drive small, high efficiency LEDs for indicator and test point circuits. The small size of the tiny package makes finding space to add this feature to even compact designs easy. Input range to Beyond Rail to Rail. The input common mode range of the LMC7211-N 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 the power design 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 LMC7211-N's common mode input range extends below ground even when powered by a single positive supply, the device can be used with large input resistors as a zero crossing detector. Low Input Currents and High Input Impedance. These characteristics allow the LMC7211-N to be used to sense high impedance signals from sensors. The characteristics also makes using the LMC7211-N in timing circuits built with large value resistors possible. 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 LMC7211-N can make directly interfacing to a sensor without the use of amplifiers or bias circuits possible. In circuits with sensors which can produce outputs in the tens to hundreds of millivolts, the LMC7211-N can compare the sensor signal with an appropriately small reference voltage. This can be done close to ground or the positive supply rail. Direct sensor interfacing can eliminate the need for an amplifier for the sensor signal. Eliminating the amplifier can save cost, space, and design time. LMC7211-N SNOS746G – MAY 2004 – REVISED DECEMBER 2025 www.ti.com

5.2 Low Voltage Operation
Comparators are the common devices by which analog signals interface with digital circuits. The LMC7211-N 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 200mV (specified) 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 5-1. 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 = 420ns and tPHL = 450ns with overdrives of 100 mV. Please refer to the performance curves for more extensive characterization.
5.3 Output Short Circuit Current
The LMC7211-N 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.
5.4 Hysteresis
If the input signal is very slow or very noisy, the comparator output can trip several times as the input signal passes through the threshold. Using positive feedback to add hysteresis to the switching can reduce or eliminate this problem. The positive feedback can be added by a high value resistor (R F). This results in two switching thresholds, one for increasing signals and one for decreasing signals. A capacitor can be added across R F to increase the switching speed and provide more short term hysteresis. This can result in greater noise immunity for the circuit. See Figure 5-2, Figure 5-3 and Figure 5-4. Note that very heavy loading of the comparator output, such as LED drive or bipolar logic gates, changes the output voltage and shift the voltage thresholds. www.ti.com LMC7211-N SNOS746G – MAY 2004 – REVISED DECEMBER 2025 Copyright © 2025 Texas Instruments Incorporated Submit Document Feedback 9 Product Folder Links: LMC7211-N

5.5 Input Protection
If input signals are likely to exceed the common mode range of the LMC7211-N, or signals can be present when power is off, damage to the LMC7211-N can occur. Large value (100k Ω to M Ω) input resistors can reduce the likelihood of damage by limiting the input currents. Since the LMC7211-N has very low input leakage currents, the effect on accuracy is small. Additional protection can require the use of diodes, as shown in Figure 5-5. Note that diode leakage current can affect accuracy during normal operation. The R-C time constant of R IN and the diode capacitance can also slow response time.

5.6 Layout Considerations
The LMC7211-N is not an especially fast comparator, so high speed design practices are not required. The LMC7211-N is capable of operating with very high impedance inputs, so take precautions to reduce noise pickup with high impedance (∼ 100kΩ and greater) designs and in electrically noisy environments. Keeping high value resistors close to the LMC7211-N and minimizing the size of the input nodes is a good practice. With multilayer designs, try to avoid long loops which can act as inductors (coils). Sensors that are not close to the comparator can need twisted pair or shielded connections to reduce noise.
5.7 Open Drain Output, Dual Versions
The LMC7221 is a comparator similar to the LMC7211-N, but with an open drain output which allows the output voltage to be different (higher or lower) than the supply voltage. The open drain output is like the open collector output of a logic gate. This makes the LMC7221 very useful for mixed voltage systems. Many systems have different voltages for the analog and microprocessor sections. Please see the LMC7221 data sheet for details. The performance of the LMC7211-N is available in dual devices. Please see the LMC6762 data sheet for details on a dual push-pull output device. For a dual device with open drain outputs, please see the LMC6772 data sheet. www.ti.com LMC7211-N SNOS746G – MAY 2004 – REVISED DECEMBER 2025 Copyright © 2025 Texas Instruments Incorporated Submit Document Feedback 11 Product Folder Links: LMC7211-N

(2) Material type: When designated, preproduction parts are prototypes/experimental devices, and are not yet approved or released for full production. Testing and final process, including without limitation quality assurance, reliability performance testing, and/or process qualification, may not yet be complete, and this item is subject to further changes or possible discontinuation. If available for ordering, purchases will be subject to an additional waiver at checkout, and are intended for early internal evaluation purposes only. These items are sold without warranties of any kind. (3) RoHS values: Yes, No, RoHS Exempt. See the TI RoHS Statement for additional information and value definition. (4) Lead finish/Ball material: Parts may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two lines if the finish value exceeds the maximum column width. (5) MSL rating/Peak reflow: The moisture sensitivity level ratings and peak solder (reflow) temperatures. In the event that a part has multiple moisture sensitivity ratings, only the lowest level per JEDEC standards is shown. Refer to the shipping label for the actual reflow temperature that will be used to mount the part to the printed circuit board. (6) Part marking: There may be an additional marking, which relates to the logo, the lot trace code information, or the environmental category of the part. Multiple part markings will be inside parentheses. Only one part marking contained in parentheses and separated by a "~" will appear on a part. If a line is indented then it is a continuation of the previous line and the two combined represent the entire part marking for that device.
