Need to increase the amplitude of op-amp output
From the comments:

... in the case of comparator the issue is of level adjustment. As this circuitry can be repeated upto 100000 times in the industry.

No. Many op-amps latch up when driven to the supply rails. Comparators are designed to be driven to the supply rails. Repeating a mistake a million times won't fix it.

Figure 1. From the datasheet we can see that with a 30 V supply driving a 2 kΩ load the max output voltage will be 26 V. They don't specify what it will be with a 5 V supply.
Most comparators feature an open collector or open-drain output and with the addition of a pull-up resistor full supply voltage can be achieved on the output.
