What are the ratings of the LM393 IC?

What are the ratings of the LM393 IC?

The ratings of the LM393 IC mainly include an amount of current, voltage & required power for that particular IC. The input voltage of this IC ranges from -0.3V to 36V This circuit uses a photoresistor for controlling the circuit of a voltage divider. When this circuit absorbs to bright light, then the output device will be turned off.

What is the purpose of the LM393 chip?

LM393 is a commonly used op amp chip, the main purpose is to be used as a voltage comparator. So LM393 is often called a voltage comparator chip. What is a voltage comparator is to compare whether the voltages of the two inputs are the same. This feature is very useful. Many electrical appliances around us use this feature.

How does the LM393 soil moisture sensor work?

LM393 is a voltage comparator. Insert the two electrodes connected to the soil moisture sensor into the soil. Because the water in the soil has certain conductivity, the change of soil moisture will cause the equivalent resistance of the soil to change, and the partial pressure will be obtained.

What does the LM393 dual differential comparator do?

The LM393 is a dual differential comparator; this means that it accepts 2 inputs for comparison. It compares these voltage inputs and determines which is the larger value. Based on this, electronic decisions can be made based on which input is greater and which is smaller.

What is the pin configuration of the LM393 IC?

What is LM393 IC : Pin Configuration, Circuit and Its Working The IC LM393 has two internally inbuilt operational amplifiers which are internally compensated with frequency. These ICs are specially designed for performing their different tasks using a single power supply. It can also execute its functions properly with a split power supply.

What is the night light circuit using LM393?

Here the LED is used as a load. The night light circuit using LM393 is shown below. This circuit uses a LED as a load, and a photoresistor is used to detect light. The resistance of the photoresistor mainly depends on the light hits on the surface.

What causes the output of the LM393 to stay low?

If connecting R7 to the “output” – being pin 1 of the LM393 – causes the output to stay low then you probably have a wiring fault, or other circuit conditions are not as you describe/expect.

What’s the common mode on a LM393 amplifier?

The common-mode input range for the 393 is 0 to supply minus 2 volts. If both inputs are above this range, the output goes low. Try adjusting R9 and/or R6 so that the voltage on the inverting input (with Q3 off) is at least 2V below the supply voltage. It’s a good idea to always have one input within the common-mode range.

What is the Red Line on the LM393?

The red line is the voltage supposed to be strangled permanently after the first hi-to-low-transition, i.e. the first time opamp goes low. The green line is the opamp output: High at first (correct), then low when triggered (correct), but then it goes high again, and this is incorrect.
