Dear All,
I have run into a bit of a problem. I am using a .1 ohm current shunt which is located between the negative terminal of my battery and the system ground of my application:
0.1 R
0V > ---/\/\/\/\-----------/\/\/\/\--------------- < +12V
|
-----

-
I wish to convert the voltage across the shunt (eg. -200 mV) into a usable analog voltage (eg. 2V). I realize an op-amp can be used, but how? I don't know much about op-amps. I know how to use them to multiply the voltage by 10, but because it is -ve with respect to ground, i am utterly clueless.
Thankyou very much,
John B
