Hi, we are trying to use the ADA4350 as the first stage amplifier for the signal from a photo diode and here are my questions.
1. If we use +/- 5V operations, it seems the -5V source noise we have from the 7660 is very big, so what is the noise requirement on -5V source for ADA4350? And do you have any low noise -5V source chip to recommend?
2. How about if we only use 5V source for the ADA4350 operations?
3. Can I use +/- 3.3V for the ADA4350?
Appreciate your help very much!
