Hi Devendhiran,
Thanks for reaching out on E2E!
Unfortunately, I can't see the images you attached. However, I can get the idea of what you're saying. You can use the Slew Rate equation on 9.3.1 to calculate the slew rate in us/V, and then take the inverse of result. This will give you the answer in V/uS, which you can use to approximate the rise time similar to Table 1.
Thanks,
Thanks,

Hi,
Thanks your reply.
If I take the inverse of slew rate (us/V) it will give 1/slew rate (V/us) - as I understood. Please correct me if my understanding is wrong.
Also, again i have attached the two images which i have added in the previous post.
Datasheet formula reference :
Modified formula reference : (Modified the individual elements to get the result in V/us)
Hi Devendhiran,
Your comment is correct, however the second equation you are providing is incorrect. Since the inverse of the slew rate is 1/slew rate, the 34 needs to be included in the denominator.
The easiest way to calculate the slew rate in V/us is to use the equation in the datasheet, and simply take the inverse of the result (1/answer).
Thanks,
Arthur Huang
