Hi all,

Well, i want to build a circuit that can convert a 20 mV signal to 10V, they told me that is what is called a transducer amp.
Pls does anyone have a schematics for this or can help doing it cos i need it asap and i don't have much time to search..

I appreciate ur help
Thank u in advance

What kind of frequency are we looking at?

Click to expand...

And what kind of input and output impedances?. Perhaps it would be an idea to mention exactly what it's for!.

Perhaps he meant converting a 20mA current loop to a 10V output.

use a 2 stage op-amp circuit. Fisrt stage inverts the signal with a gain of 50, the second inverts it agaon with a gain of 10. very simple
