I'm just wondering if there's an op-amp that can amplify few micro volts to volts...As I need to design an op-amp integrator that can amplify few micro volts to volts... Please if there's just tell me the model name.. Thanks a lot ...
Could you quantify your requirement a bit better? How many microvolts, and how many volts? It will be easier if you use multiple devices, rather than one, considering the amount of amplification.
I believe you might want to do your amplification, and then integrate the result. Do you have a circuit you can post for commentary?
I need to desgin an integrator where the in the put to this integrator will be in terms of micro volts.. For example, 60 micro volts of input and the integrated result would be 6 volts.This means the input will always be in terms of microvolts and the integrator should be able to amplify it to volts .Just like when ideal integrator works.
Your function is amplification - making a 60 microvolt input into a 6 volt output. I would go for a gain of 100,000 in two steps - 100 and 1000. An OPA2134 dual op amp might do very well.
Yeah what you said is correct, but my input keeps changing, it's not constant coz if it's constant then my op-amp will go into sautration. My input is in terms of micro volts and keeps changing.. I would like to go for a gain of 100,000 but do u think there's a way to do that in one step rather two steps??
Thanks a lot for your reply....
