Where are the voltage inputs on the lm311?
An LM311 is a 8-pin chip. The pinout is shown below: The LM311 has 2 power inputs. These are labeled VCC and VEE. V CC, pin 8, is where the positive terminal of the voltage supply gets inserted into.
When to use the potentiometer on the lm311?
So this is as basic of a circuit as you can get with the LM311. Since this is a night light circuit, we want the LED on when it is dark and off during daylight conditions. So we use the potentiometer as a calibrator. We tune it so that the LED is off during lit conditions and on during dark conditions.
How does the lm311 work as a comparator?
The LM311 is a single comparator. This means it is composed internally of one comparator. It compares these voltage inputs and determines which is the larger value.
What are the connections of the lm311 comparator?
The basic comparator has five connections: Inverting input, non-inverting input, as well as an output, positive power supply, and negative power supply. Because the LM311 can operate from single rail supplies, and we are going to use it that way, this is how we’ll move forward.
Is the LM111 voltage comparator compatible with RTL?
The LM111, LM211 and LM311 are voltage comparators that have input currents nearly a thousand times lower than de- vices like the LM106 or LM710. ± 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.
Why is the lm311 used as a comparator?
LM311 is a commonly used linear comparator. The LM311 is cost-effective, and this is the reason why it is widely used in various comparison circuits. This blog uses take the advantage of the LM311 to introduce and analyze a series of circuits that using the LM311 such as light control and water leak detection.
How to drive DC motor with STM32?
I have a 6 volts DC motor and want to control it with stm32 and change the rotation direction. Previously, I designed an H-bridge, I used for the upper part IRF9630 and the lower part IRF630 ,I connected the HIGH part to 12V and the motor didn’t work and even move. After that I changed MOSFETs and used IRF4905 and IRFz44n .But it didn’t work again.
