Hi Guys,
It has been quite sometime since I have dealt with electronics. But, I kinda have this question lingering in my mind. What is the difference between these setups I am describing below. I would really appreciate it if someone can explain. I am unable to understand or am I looking at it differently.
Basically, I have an opamp in non inverting setup to give and output of 24V when input is 5V and 0V when input is 0V. Using an Opamp for digital setup and especially for working like a switch is not ideal I presume. But now that I have done it, I want to make it work until the next design.
Difference between :-
A non inverting opamp with R1=10k and R2=100k.
A non inverting opamp with R1=1k and R2=10k
Both have gain of 10. I am assuming that there will be current limitations. Although for my requirement, a gain of 5 would suffice with R1=1k and R2=4.7k, but I didnt realize this before while designing.
My requirement is 24V output @ 11.2mA. My source or input is 5V @ 5mA. Any help or explaination would be amply appreciated.
Thanks!
