I need to obtain or build a small pre amplifier to use between the output of a small accelerometer ( output about 15mV)and the line-in of the soundcard of my computer. The output impedance of the accelerometer is about 75 ohms. It is important that it have very low noise and be very stable and have a gain of around 100 to 200.
Does anyone know where I can get such a circuit or where I can buy one ready made ( if its not too expensive)
Many thanks in advance.

Look in the applications sections of the websites for all Opamp manufacturers. They all have an app note on such a circuit. Some have Opamps specially designed for this application.
