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.

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. Please refer to the performance curves for more extensive characterization. 8 Submit Documentation Feedback Copyright © 1999–2013, Texas Instruments Incorporated Product Folder Links: LMC7221 LMC7221 www.ti.com SNOS748E – SEPTEMBER 1999 – REVISED MARCH 2013 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.
