Multiple vs single instrumentation opamp.

[pharaoh_04]

Dear all,

I am very newbie to the electronic field. However, I am constructing an amplifying circuit for strain gauge measurement.

Then, this question comes to my consideration. What are the differences between using a single op-amp with high gain when compared to a multiple op-amps connected-in-series (with an identical total gain).

For example: [a op-amp with 6,000-gained ] vs [three of 2,000-gained op-amps]

It should be also useful if there is any recommended books or articles on this topic.

Thank you in advance,

Regards,

Dave covered this a while back.  If you have room, multiple opamps can give you better performance.
