How an eight-pin dual in-line package is shortly named? The maximum generally used op-amp is IC741. The 741 op-amp is a voltage amplifier, it inverts the enter voltage on the output, and may be discovered nearly anywhere in digital circuits.
Pin Configuration:
Let`s see the pin configuration and checking out of 741 op-amps. Usually, that is numbered counterclockwise across the chip. It is an eight-pin IC. They offer advanced overall performance in integrator, summing amplifier, and standard comments packages. These are excessive advantage op-amp; the voltage at the inverting entry may be maintained nearly identical to Vin.

LM324
LM324 is a quad op-amp incorporated circuit with excessive stability, and bandwidth which turned into designed to perform from an unmarried strength deliver over an extensive variety of voltages. They have a few distinct benefits over popular operational amplifier kinds in unmarried delivery packages. It is a 14-pin twin in-line package and carries 4 internally compensated and level operational amplifiers, proven in the figure.
- Pin 1, 7, eight, and 14 are the outputs of the comparator
- Pin 2, 6, nine, and thirteen are the inverting inputs of the compactor
- Pin three, 5, 10, and 12 are non-inverting inputs of the comparator
- Pin eleven is ground (0V)
- Pin four is deliver voltage; 5V
Features:
- Internally frequency compensated for team spirit advantage
- Large DC voltage advantage of a hundred dB
- Wide bandwidth 1 MHz
- Wide strength deliver variety: Single deliver 3V to 32V
- Essentially unbiased of deliver voltage
- Differential enter voltage variety identical to the strength delivered voltage
- Large output voltage swing 0V to V+ − 1.5V
Potential dividers of LM323 are linked to the inverting and noninverting inputs of the op-amp to provide a few voltages at those terminals. The supply voltage is given to +V and –V is attached to the ground. The output of this comparator might be good judgment excessive if the non-inverting terminal enter is more than the inverting terminal enter of the comparator. When the inverting entry is extra than the non-inverting then good judgment low (0) might be the output.
Working of LM324:
When the strength is implemented to the non-inverting terminal that’s much less than the inverting voltage of op-amp then the output turns into 0 because of this that there’s no modern float. Because we already recognize that when “+ > – = 1”. Here the `+ `signal shows the non-inverting terminal and the `-` signal shows the inverting terminal.
If the non-inverting voltage is more than the inverting voltage then the output might be excessive.
This output of LM324 is internally linked to a few resistance and it has a few associations withinside the IC, which makes numerous distinctions to different comparators.
It is internally pulled up, so no want for any resistor connection from the delivery.
3. LM339
The LM339 is the maximum generally used comparator, designed to be used in stage detection, low−stage sensing, and reminiscence packages in automobile and commercial digital packages. It has 4 built-in comparators; it compares enter voltage ranges and offers virtual output to reveal the larger one.
These comparators moreover have a unique function in that the enter common-mode voltage variety consists of ground, despite the reality that they may be operated from an unmarried strength deliver voltage.
- Pin 1, 2, thirteen, and 14 are the outputs of the comparator
- Pin three is delivered voltage; 5V
- Pin four, 6, eight, and 10 are inverting inputs of the comparator
- Pin 5, 7, nine, and eleven are non-inverting inputs of the comparator
- Pin 12 is ground; (0V)
Features:
- Signal or twin delivers operation
- Wide running deliver variety (VCC=2V~36V)
- Max Rating: 2 V to 36 V
- Tested to 30 V: Non-V Devices
- Input common-mode voltage consists of ground
- Low delivers modern drain (IF=0.8mA)
- Open collector outputs for stressed and connection
- Low enter bias modern 25nA
The low output saturation voltage
Output well matched with TTL, DTL, and CMOS good judgment system
Differential enter voltage variety identical to the strength delivered voltage

The supply voltage is given to +V and –V is attached to the ground.

Because we already recognize that when “+ > – = 1”. Here the `+ `signal shows the non-inverting terminal and the `-` signal shows the inverting terminal.
If the non-inverting voltage is more than the inverting voltage then the modern float might be withinside the device.
The LM339 acts as an open collector that`s why we linked the resister from the delivery, if we dispose of the resister then there’s no modern float withinside the circuit.
4. LM258
The LM358 op-amps are utilized in transducer amplifiers, dc advantage blocks, and all of the traditional op-amp circuits which now may be extra without problems carried out in unmarried strength deliver structures. For example, the LM358 op-amp may be at once operated off of the website developer popular +5V strength deliver voltage that’s used as part of virtual structures and could without problems offer the specified interface electronics without having the extra ±15V strength supplies.
