LM111, LM211, LM311 Differential Comparators
1 Features
3 Description
•
•
•
•
•
•
The LM111, LM211, and LM311 devices are single
high-speed voltage comparators. 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.

Unless otherwise noted, all characteristics are measured with BALANCE and BAL/STRB open and EMIT OUT grounded. Full range for
LM111 is –55°C to 125°C, for LM211 is –40°C to 85°C, for LM211Q is –40°C to 125°C, and for LM311 is 0°C to 70°C.
All typical values are at TA = 25°C.
The offset voltages and offset currents given are the maximum values required to drive the collector output up to 14 V or down to 1 V
with a pullup resistor of 7.5 kΩ to VCC+. These parameters actually define an error band and take into account the worst-case effects of
voltage gain and input impedance.
The strobe must not be shorted to ground; it must be current driven at –3 mA to –5 mA (see Figure 18 and Figure 31).

8 Detailed Description
8.1 Overview
The LM111, LM211 and LM311 are voltage comparators that have input currents nearly a thousand times lower
than legacy standard devices. 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.

8.3 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.

9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. 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.

9.2.2.1 Input Voltage Range
When choosing the input voltage range, consider the input common mode voltage range (VICR). 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.

10 Power Supply Recommendations
For fast response and comparison applications with noisy or AC inputs, use a bypass capacitor on the supply pin
to reject any variation on the supply voltage. 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).
