LM111QML Voltage Comparator General Description Features 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 supplies 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 voltages up to 50V at currents as high as 50 mA. Both the inputs and the output 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. Available with radiation guaranteed 50 krad(Si) -- High Dose Rate 100 krad(Si) -- Low Dose and ELDRS Free Operates from single 5V supply Input current: 200 nA max. over temperature Offset current: 20 nA max. over temperature Differential input voltage range: 30V Power consumption: 135 mW at 15V Power supply voltage, single 5V to 15V Offset voltage null capability Strobe capability Ordering Information NS PART NUMBER SMD PART NUMBER NS PACKAGE NUMBER PACKAGE DESCRIPTION LM111E-SMD 5962-8687701Q2A E20A 20LD Leadless Chip Carrier LM111H-SMD 5962-8687701QGA H08C 8LD TO-99 Metal Can LM111J-8-SMD 5962-8687701QPA J08A 8LD CERDIP LM111WG-SMD 5962-8687701QZA WG10A 10LD Ceramic SOIC LM111E/883 E20A 20LD Leadless Chip Carrier LM111H/883 H08C 8LD TO-99 Metal Can LM111J-8/883 J08A 8LD CERDIP LM111J/883 J14A 14LD CERDIP LM111W/883 W10A 10LD CERPACK LM111WG/883 WG10A 10LD Ceramic SOIC LM111HLQMLV (Note 12) High Dose Rate ONLY 5962L0052401VGA 50k rd(Si) H08C 8LD TO-99 Metal Can LM111J-8LQMLV (Note 12) High Dose Rate ONLY 5962L0052401VPA 50k rd(Si) J08A 8LD CERDIP LM111WGLQMLV (Note 12) High Dose Rate ONLY 5962L0052401VZA 50k rd(Si) WG10A LM111WLQMLV (Note 12) High Dose Rate ONLY 5962L0052401VHA 50k rd(Si) W10A 10LD CERPACK LM111HRLQMLV (Note 14) ELDRS Free ONLY 5962R0052402VGA 100k rd(Si) H08C 8LD TO-99 Metal Can LM111J-8RLQMLV (Note 14) ELDRS Free ONLY 5962R0052402VPA 100k rd(Si) J08A 8LD CERDIP LM111WGRLQMLV (Note 14) ELDRS Free ONLY 5962R0052402VZA 100k rd(Si) WG10A LM111WRLQMLV (Note 14) ELDRS Free ONLY 5962R0052402VHA 100k rd(Si) W10A (c) 2008 National Semiconductor Corporation 201285 10LD Ceramic SOIC 10LD Ceramic SOIC 10LD CERPACK www.national.com LM111QML Voltage Comparator June 30, 2008 LM111QML Connection Diagrams Metal Can Package 20128506 Note: Pin 4 connected to case Top View See NS Package Number H08C Dual-In-Line Package Dual-In-Line Package 20128534 Top View See NS Package Number J08A 20128535 Top View See NS Package Number J14A 20128533 See NS Package Number W10A, WG10A 20128573 See NS Package NumberE20A www.national.com 2 LM111QML Schematic Diagram (Note Pin connections shown on schematic diagram are for H08 package. ) 20128505 Note 1: Pin connections shown on schematic diagram are for H08 package. 3 www.national.com LM111QML Absolute Maximum Ratings (Note 2) Positive Supply Voltage Negative Supply Voltage Total Supply Voltage Output to Negative Supply Voltage GND to Negative Supply Voltage Differential Input Voltage Sink Current Input Voltage (Note 3) Power Dissipation (Note 4) 8 LD CERDIP 8 LD Metal Can 10 LD CERPACK 10 LD Ceramic SOIC 20 LD LCC Output Short Circuit Duration Maximum Strobe Current +30.0V -30.0V 36V 50V 30V 30V 50mA 15V 400mW @ 25C 330mW @ 25C 330mW @ 25C 330mW @ 25C 500mW @ 25C 10 seconds 10mA -55C TA 125C Operating Temperature Range Thermal Resistance JA 8 LD CERDIP (Still Air @ 0.5W) 8 LD CERDIP (500LF/Min Air flow @ 0.5W) 8 LD Metal Can (Still Air @ 0.5W) 8 LD Metal Can (500LF/Min Air flow @ 0.5W) 10 Ceramic SOIC (Still Air @ 0.5W) 10 Ceramic SOIC (500LF/Min Air flow @ 0.5W) 10 CERPACK (Still Air @ 0.5W) 10 CERPACK (500LF/Min Air flow @ 0.5W) 14 LD CERDIP (Still Air @ 0.5W) 14 LD CERDIP (500LF/Min Air flow @ 0.5W) 20 LD LCC (Still Air @ 0.5W) 20 LD LCC (500LF/Min Air flow @ 0.5W) 134C/W 76C/W 162C/W 92C/W 231C/W 153C/W 231C/W 153C/W 97C/W 65C/W 90C/W 65C/W JC 8 LD CERDIP 8 LD Metal Can Pkg 10 LD Ceramic SOIC 10 LD CERPACK 14 LD CERDIP 20 LD LCC 21C/W 50C/W 24C/W 24C/W 20C/W 21C/W -65C TA 150C Storage Temperature Range Maximum Junction Temperature Lead Temperature (Soldering, 60 seconds) Voltage at Strobe Pin 175C 300C V+ = -5V Package Weight (Typical) 8 LD Metal Can 8 LD CERDIP 10 LD CERPACK 10 LD Ceramic SOIC 14 LD CERDIP 20 LD LCC ESD Rating (Note 5) 965mg 1100mg 250mg 225mg TBD TBD 300V www.national.com 4 LM111QML Recommended Operating Conditions Supply Voltage VCC = 15VDC -55C TA 125C Operating Temperature Range Quality Conformance Inspection Mil-Std-883, Method 5005 - Group A Subgroup Description Temperature (C) 1 Static tests at +25 2 Static tests at +125 3 Static tests at -55 4 Dynamic tests at +25 5 Dynamic tests at +125 6 Dynamic tests at -55 7 Functional tests at +25 8A Functional tests at +125 8B Functional tests at -55 9 Switching tests at +25 10 Switching tests at +125 11 Switching tests at -55 5 www.national.com LM111QML LM111/883 Electrical Characteristics DC Parameters The following conditions apply, unless otherwise specified.

However, when the input signal is a voltage ramp or a slow sine wave, or if the signal source impedance is high (1 k to 100 k), the comparator may burst into oscillation near the crossing-point. This is due to the high gain and wide bandwidth of comparators like the LM111. To avoid oscillation or instability in such a usage, several precautions are recommended, as shown in Figure 1 below. 1. 2. 3. 4. 5. 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 F 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. 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. 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. 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 k, 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. Since feedback to almost any pin of a comparator can result in oscillation, the printed-circuit layout should be 6. 7. 8. 19 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 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 F 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.) 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 100, such as 50 k, it would not be reasonable to simply increase the value of the positive feedback resistor above 510 k. The circuit of Figure 3 could be used, but it is rather awkward. See the notes in paragraph 7 below. 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 82 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 k pot and 3 k resistor as shown. These application notes apply specifically to the LM111 and are applicable to all high-speed comparators in general, (with the exception that not all comparators have trim pins). www.national.com LM111QML Application Hints LM111QML 20128529 Pin connections shown are for LM111H in the H08 hermetic package FIGURE 1.
