Which is the output of the lm311 comparator?
LM311 is a single-channel comparator. When using it, connect the reference voltage and the compared signal voltage to its non-inverting and inverting input terminals (pin 2 and pin 3), and its output is the result of the comparison. If you want the foward output result, pin 7 is connected to the positive power supply and pin 1 is the output.
What’s the difference between lm311 and LM393?
If you want the foward output result, pin 7 is connected to the positive power supply and pin 1 is the output. If the result is to be output in reverse, pin 1 is grounded and pin 7 is the open collector output. lm311 and lm393 are both voltage comparators, so what is the difference between them?
Which is an example of an lm311 IC?
One of the simplest application LM311 IC is a zero crossing detector circuit which is shown as: As you know, like other comparators, if the voltage at the non-inverting input is greater than inverting terminal, the output comparator will be high.
What are the inputs and outputs of a comparator?
The comparator has 2 inputs and one output. One input, pin 2, is the noninverting terminal. The second input, pin 3, is the inverting terminal voltage. We will connect a reference voltage to the noninverting terminal. And we will attach a voltage divider circuit to the inverting terminal of the comparator.
What is the current draw on the lm311?
Current draw is different for different supply situations, but was measured on the workbench as 1.19mA from a +5V supply with no load. The LM311 is quite an old device, and the maximum input differential (the difference between the voltages at the inputs) is 30V (+/- 15V).
How much voltage can a lm311 transistor handle?
The simplified diagram shows the output of the LM311 as an N-channel transistor with open collector and emitter terminals. It can handle a maximum of 40V at 50mA, which means it can switch many relays on its own, or be used with an external transistor for switching larger loads.
