Hello guys, I have a problem with my already made circuit, i want to replace my ADA4004-2 op amp with a same pin configuration single ended supply op amp of range 0-15v. Please its urgent. Thanks
I tried it but my input signal is in mV and min value op amp would give when applied +15V n Gnd is 2V. So can't use same op amp. I have alrdy ordered PCBs so have no other choice. My schematic can be seen in AN687. Op amp with A3 output
- there are several AN687 from several manufacturers.
- I used Analog.com but there is neither ADA4004 nor any other OPAMP
- what does this mean: "Op amp with A3 output"?
Again: to further help you we need your specificatins.
I am really sorry for not posting the circuit earlier, here it is
only difference is that Op amp used in my circuit is ADA4004-2. And i want a single supply op amp that may detect mV when applied with 0 and +15V without anychange in my PCB

I am talking about the op amp with differential inputs
The ADA4004-2 has the industry standard pin configuration for dual opamps. This means there are literally hundreds and hundreds of replacements from many vendors.
But as Klaus mentions, you have to make a parametric search. In the old days, that meant poring over hundreds of pages of datasheets, and that is if you had a good library with many databooks.
Nowdays, you can go to a website for Texas Instruments, Linear Technologies, OnSemi, Microchip..etcetera. And make a parametric search.
