What is a LM311?

What is a LM311?

LM311 is a voltage comparator with high speed. It is able to perform tasks over a large range of voltages. Its output levels are compatible with MOS circuits. Relays and lamps can be controlled by LM 311 when it is operating at 50V and 50mA as well.

Whats a comparator do?

A comparator circuit compares two voltages and outputs either a 1 (the voltage at the plus side) or a 0 (the voltage at the negative side) to indicate which is larger. Comparators are often used, for example, to check whether an input has reached some predetermined value.

What is IC 339?

The IC 339, also popularly written as LM339, is a quad comparator IC. Meaning, it includes 4 separate voltage comparators whose inputs and outputs are appropriately terminated via the respective external pins of the IC package, as shown below.

What does a LM311 comparator do?

The LM111, LM211, and LM311 devices are single high-speed voltage comparators. 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−.

What is balance strobe?

The strobe pin allows you to turn off the output stage. The balance pin are for canceling the DC-offset voltage. The Vee pin is use as a voltage supply pin because pin 1 (GND) can be used as a emitter output.

How many pins do 747 amplifier have?

14 pin
Pin Configuration of LM747 IC. The LM 747 IC is a 14 pin dual op-amp device. The pin configuration with the description for every pin in the op-amp1 as well as op-amp2 is explained below.

What are the types of comparators?

Types of Comparators

• Mechanical Comparator.
• Mechanical-Optical Comparator.
• Reed Type Comparator.
• Electrical-Electronic Comparator.
• Pneumatic Comparator.

Is IC 339 a positive variable voltage regulator?

The IC LM399 has positive and negative pins which are pin-3 and pin12 as shown in the circuit. Simultaneously, the voltage supply from the battery will flow through the potentiometer VR1 to the non- inverting terminals (pin5) of the IC.

How many comparators does 339 IC have?

Exercise :: Linear-Digital ICs – General Questions

How do voltage comparators work?

Comparator Circuit Working and Applications. Generally, in electronics, the comparator is used to compare two voltages or currents which are given at the two inputs of the comparator. That means it takes two input voltages, then compares them and gives a differential output voltage either high or low-level signal.

What is strobe in opamp?

The strobe pin allows you to turn off the output stage. The balance pin are for canceling the DC-offset voltage.

How does the lm311 work?

The LM311 compares these voltage inputs and determines which value is larger. On this basis, you can make electronic decisions based on which input is larger and which is smaller.

What are the features of LM 311 IC?

LM-311 has several different features. These features include fast response time, strobe capability, wide voltage supply ranges, maximum input current, operating at single 5V power supply ranges, low power consumption, large input differential voltages etc. Several different applications are associated with LM 311 IC.

What is the operating temperature range of LM 311?

LM 311 can operate from 0 degree Celsius to 70 degree Celsius. LM-311 has several different features. These features include fast response time, strobe capability, wide voltage supply ranges, maximum input current, operating at single 5V power supply ranges, low power consumption, large input differential voltages etc.

What is the lm311 differential comparison operational amplifier?

The lm311 differential comparison operational amplifier is a very old Ti comparison IC which has been used in voltage comparison with electronic design for a long time. Any operational amplifier can be used as a voltage comparator, but lm311 proves its advantage by placing an output transistor in its package.
