Single Comparators
The ability to operate from a single power supply of 5.0 V to 30 V or
$15 V split supplies, as commonly used with operational amplifiers,
makes the LM211/LM311 a truly versatile comparator. Moreover, the
inputs of the device can be isolated from system ground while the
output can drive loads referenced either to ground, the V
CC
or the V
EE
supply. This flexibility makes it possible to drive DTL, RTL, TTL, or
MOS logic. The output can also switch voltages to 50 V at currents to
50 mA, therefore, the LM211/LM311 can be used to drive relays,
lamps or solenoids.

1. Offset voltage, offset current and bias current specifications apply for a supply voltage range from a single 5.0 V supply up to ±15 V supplies.
2. This rating applies for ±15 V supplies. The positive input voltage limit is 30 V above the negative supply. The negative input voltage limit is
equal to the negative supply voltage or 30 V below the positive supply, whichever is less.
3. The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with a 1.0 mA
load. Thus, these parameters define an error band and take into account the “worst case” effects of voltage gain and input impedance.
4. The response time specified is for a 100 mV input step with 5.0 mV overdrive.
5. Do not short the strobe pin to ground; it should be current driven at 3.0 mA to 5.0 mA.
