Product Summary
This product is a low-noise AC amplifier that can be used for noise evaluation of DC power output and DC signal in board design. It is possible to amplify and observe uV-order noise and minute signals superimposed on a maximum 40V DC signal. Since it is equipped with a unique circuit that achieves both low noise performance and input protection, it is possible to apply a large DC voltage even though it is a low noise amplifier that can measure minute signals.
