Highly Flexible Voltage 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 VCC or the VEE 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. Thus the LM211/LM311 can be used to drive relays, lamps or solenoids.

DESCRIPTION
The LM111 series are voltage comparators that have input currents approximately a hundred times lower than devices like the µA710. They are designed to operate over a wider range of supply voltages; from standard ±15 V op amp supplies down to a single 3 V supply.
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 50mA.
Both the inputs and the outputs of the LM111 series 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. Although slower than the µA710 (200 ns response time versus 40 ns), the devices are also much less prone to spurious oscillations. The LM111 series has the same pin configuration as the µA710 series.

FEATURES
• Operates from single 3 V supply (LM311B)
• Maximum input bias current: 150 nA (LM311: 250 nA)
• Maximum offset current: 20 nA (LM311: 50 nA)
• Differential input voltage range: ±30 V
• Power consumption: 135 mW at ±15 V
• High sensitivity: 200 V/mV
• Zero crossing detector

APPLICATIONS
• Precision squarer
• Positive/negative peak detector
• Low voltage adjustable reference supply
• Switching power amplifier

General Description
The LM111, LM211 and LM311 are voltage comparators that have input currents nearly a thousand times lower than devices like the LM106 or LM710. They are 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. 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 50V 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 OR’ed. Although slower than the LM106 and LM710 (200 ns response time vs 40 ns) the devices are also much less prone to spurious oscillations. The LM111 has the same pin configuration as the LM106 and LM710.
The LM211 is identical to the LM111, except that its performance is specified over a −25˚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.

Features
■ Operates from single 5V supply
■ Input current: 150 nA max. over temperature
■ Offset current: 20 nA max. over temperature
■ Differential input voltage range: ±30V
■ Power consumption: 135 mW at ±15V
