These devices are designed to operate from a wide range of powersupply voltages, including ±15-V supplies for operational amplifiers and 5-V supplies for logic systems. The output levels are compatible with most TTL and MOS circuits. These comparators are capable of driving lamps or relays and switching voltages up to 50 V at 50 mA. All inputs and outputs can be isolated from system ground. The outputs can drive loads referenced to ground, VCC+ or VCC−. Offset balancing and strobe capabilities are available, and the outputs can be wire-OR connected. If the strobe is low, the output is in the off state, regardless of the differential input. 1 • Fast Response Time: 165 ns Strobe Capability Maximum Input Bias Current: 300 nA Maximum Input Offset Current: 70 nA Can Operate From Single 5-V Supply Available in Q-Temp Automotive – High-Reliability Automotive Applications – Configuration Control and Print Support – Qualification to Automotive Standards On Products Compliant to MIL-PRF-38535, All Parameters Are Tested Unless Otherwise Noted.

They are also designed to operate over a wider range of supply voltages: from standard ±15V op amp supplies down to the single 5-V supply used for IC logic. Their output is compatible with RTL, DTL and TTL as well as MOS circuits. Further, they can drive lamps or relays, switching voltages up to 50 V at currents as high as 50 mA. Both the inputs and the outputs of the LM111, LM211 or the LM311 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 ORed. The LM211 is identical to the LM111, except that its performance is specified over a −40°C to +85°C temperature range instead of −55°C to +125°C. The LM311 has a temperature range of 0°C to +70°C. The LM211Q has a temperature range of −40°C to +125°C. 8.2 Functional Block Diagram Component Count Resistors Diodes EPI FET Transistors BAL/STRB BALANCE 450 Ω 450 Ω 20 2 1 22 VCC+ 2.4 kΩ 750 Ω 2.4 kΩ 600 Ω 70 Ω 1.2 kΩ 1.2 kΩ IN+ 4 kΩ COL OUT IN− 400 Ω 130 Ω 60 Ω 600 Ω 450 Ω 250 Ω 200 Ω 4Ω 2 kΩ EMIT OUT VCC− Copyright © 2016, Texas Instruments Incorporated 10 Submit Documentation Feedback Copyright © 1973–2017, Texas Instruments Incorporated Product Folder Links: LM111 LM211 LM311 LM111, LM211, LM311 www.ti.com SLCS007K – SEPTEMBER 1973 – REVISED MARCH 2017 8.3 Feature Description LMx11 consists of a PNP input stage to sense voltages near VCC–. It also contains balance and strobe pins for external offset adjustment or trimming. The input stage is followed by a very high gain stage for very fast response after a voltage difference on the input pins have been sensed. This is then followed by the output stage that consists of an open collector NPN (pulldown or low-side) transistor. Unlike most open drain comparators, this NPN output stage has an isolated emitter from VCC–, allowing this device to set the VOL output value for collector output. 8.4 Device Functional Modes 8.4.1 Voltage Comparison The LMx11 operates solely as a voltage comparator, comparing the differential voltage between the positive and negative pins and outputting a logic low or high impedance (logic high with pullup) based on the input differential polarity.

TI’s customers are responsible for determining suitability of components for their purposes. Validate and test the design implementation to confirm system functionality. 9.1 Application Information A typical LMx11 application compares a single signal to a reference or two signals against each other. Many users take advantage of the open-drain output to drive the comparison logic output to a logic voltage level to an MCU or logic device. The wide supply range and high voltage capability makes LMx11 optimal for level shifting to a higher or lower voltage. 9.2 Typical Application VCC+ 20 kΩ Output Input VCC− Copyright © 2016, Texas Instruments Incorporated Figure 13.

Operation outside of this range can yield incorrect comparisons. The following list describes the outcomes of some input voltage situations. • • • • When both IN– and IN+ are both within the common-mode range: – If IN– is higher than IN+ and the offset voltage, the output is low and the output transistor is sinking current – If IN– is lower than IN+ and the offset voltage, the output is high impedance and the output transistor is not conducting When IN– is higher than common mode and IN+ is within common mode, the output is low and the output transistor is sinking current When IN+ is higher than common mode and IN– is within common mode, the output is high impedance and the output transistor is not conducting When IN– and IN+ are both higher than common mode, the output is undefined 9.2.2.2 Minimum Overdrive Voltage Overdrive voltage is the differential voltage produced between the positive and negative inputs of the comparator over the offset voltage (VIO). To make an accurate comparison the Overdrive voltage (VOD) must be higher than the input offset voltage (VIO). Overdrive voltage can also determine the response time of the comparator, with the response time decreasing with increasing overdrive. Figure 14 and Figure 15 show positive and negative response times with respect to overdrive voltage. 9.2.2.3 Output and Drive Current Output current is determined by the pullup resistance and pullup voltage. The output current produces a output low voltage (VOL) from the comparator, in which VOL is proportional to the output current. Use Figure 5 to determine VOL based on the output current. The output current can also effect the transient response. 9.2.2.4 Response Time The load capacitance (CL), pullup resistance (RPULLUP), and equivalent collector-emitter resistance (RCE) levels determine the transient response. Equation 1 approximates the positive response time. Equation 2 approximates the negative response time. RCE can be determine by taking the slope of Figure 5 in the linear region at the desired temperature, or by Equation 3. tP @ RPULLUP ´ CL (1) tN @ RCE ´ CL V RCE = OL IOUT (2) where • • VOL is the low-level output voltage IOUT is the output current Copyright © 1973–2017, Texas Instruments Incorporated Product Folder Links: LM111 LM211 LM311 (3) Submit Documentation Feedback 13 LM111, LM211, LM311 SLCS007K – SEPTEMBER 1973 – REVISED MARCH 2017 www.ti.com 9.2.3 Application Curves µ µ Figure 14.

This variation can affect the common-mode range of the comparator input and create an inaccurate comparison. 11 Layout 11.1 Layout Guidelines To create an accurate comparator application without hysteresis, maintain a stable power supply with minimized noise and glitches, which can affect the high level input common-mode voltage range. To achieve this accuracy, add a bypass capacitor between the supply voltage and ground. Place a bypass capacitor on the positive power supply and negative supply (if available). 11.2 Layout Example Ground Bypass Capacitor Negative Supply or Ground Only needed for dual power supplies EMIT OUT 1IN+ 1INí VCC- 1 8 2 7 3 6 4 5 0.1µF VCC+ COL OUT BAL/STROB BALANCE Positive Supply 0.1µF Ground Copyright © 2016, Texas Instruments Incorporated Figure 34.
