It is an Operational Amplifier (Op-amp) consists of four channels. Today, I am going to elaborate about the Introduction to LM324.

Integrator, Differentiator, Summer, adder, Voltage follower, etc.Hello everyone! I hope you all will be absolutely fine and having fun.

An orientation example for two temperature sensing RT1 and RT2,Ībove is the supply configuration for both single and dual supply connections. If the temperature is to be monitored at three or four positions of the motor then LM324 can be used in below configuration. Thus, Output is LOW and it can drive a motor OFF through a transistor or relay. Thus, Output is HIGH and it can drive a motor ON through a transistor or relay.Īt Temperature = above 70˚C, RT=3kὨ. Here a thermistor does the job whose resistance varies with temperature.īelow will be a simple circuit connection to sense temperature and control a system.Īt Temperature = 25˚C, RT=10kὨ.

Check out Difference between Op-Amp and Comparator. This is the place where op amp operates as a positive comparator. So, our job is to shut down the system if the temperature increases beyond rated. As the load increases the current increases which in turn increases the temperature of the motor. Generally, op-amps can perform mathematical operations.Ĭonsider, an motor running with a variable load. The operating temperature ranges from 0˚C to 70˚C at ambient whereas the maximum junction temperature can be upto 150˚C.

The default input offset voltage is very low which is of magnitude 2mV. The differential input voltage range can be equal to that of power supply voltage. LM324 is a Quad op-amp IC integrated with four op-amps powered by a common power supply. Soldering pin temperature – 260 ˚C (for 10 seconds – prescribed).

Operating ambient temperature – 0˚C to 70˚C.Single supply for four op-amp operation enables reliable operation.Integrated with four Op-Amps in a single package.LM324 Quad Op-Amp IC Features and Specifications
