Current Amplifiers
In order to achieve an extremely low noise performance very high gains were chosen, while nevertheless minimizing the associated bandwidth reduction.Thus, as a result of our sophisticated development efforts we can offer a professional "High-End" Current Amplifier line. The noise performance of our products surpasses by far that of conventionally designed OpAmp current-to-voltage converters at the corresponding bandwidth.
