Hello,

 

I need to sample an analog signal ranging from -5 V to +15 V having an estimated bandwidth of 8 MHz.

 

I thought of getting an AD9650-25. is that a good decision or is there something more appropriate?

 

Using the Diff-Amp Calculator, I found the ADA4930 and ADA4940. Will does work and which one is better?

Can I use an ADM7150-5.0 for the ADA4930/ADA4940 VCC and also connect it to VinN?

 

As I'm new to analog circuit design, any hints are more than welcome.

 

many thanks
