Ultra-low noise, excellent stability, wideband ultra-small signal detection amplifier
The "SA Series" is a low-noise amplifier that pursues technology to suppress factors that hinder measurements, such as noise and environmental influences, to the utmost limit. We offer the voltage input "SA-200 Series/SA-400 Series," which achieves low noise that was not attainable with previous amplifiers, and the current input "SA-600 Series," which realizes high gain and wide bandwidth. Please choose the model that matches the signals from your sensor. *For more details, please refer to the PDF materials or feel free to contact us.
