Hey Everyone,

I'm looking for an instrumentation amplifier IC that can take ground as a rail for power. So far I've been using an INA111.

Ideally, I would be able to use +9V for V+, and 0V for V-. Do these exist? If so, anyone know where I can find one?

Much thanks,

alex

PS: the reason I need this is because I would like to power if off one 9V battery instead of 2

 

If you search the phrase "single supply instrumentation amplifier" you'll have an answer.

 

Excellent! Thank you.
