    Hello all:

    I have a small project but I have some issues and need some help.

    A sensor creates a voltage diff between 0-15mV. I want to use a DAQ from National


    However, the minimum input is ±1V.

    How I can amplifier the voltage to match with the minimum input for DAQ?

    I have read some info about op amp, Could you help me with some basic concepts to fulfill my project?

    Oh, this is the sensor:

    An opamp is definitely the way to go. Google opamp non-inverting amplifier. All you need is two resistors to set the gain. If you want to use a single supply, be sure to get an opamp with rail-to-rail inputs and outputs.
