A super high-sensitivity, compact, and reasonably priced current sensing amplifier (current-voltage conversion amplifier) that can measure picoamperes!
Through clever circuit design and careful selection of components, we have achieved a balance between high performance, compact size, and low cost. The combination of ultra-low input current operational amplifiers and high-precision ultra-high resistors converts picoamperes into voltage. With input protection, the power supply operates with a reasonable DC voltage supply for high signal-to-noise ratio performance, and battery operation allows for even lower noise performance. Please consult us regarding the production of resistance values other than 1GΩ. When using two or more units connected to a common 0V line from a single power supply, be sure to include decoupling capacitors. Power supply decoupling: T-02ADPVD01 is also available for sale.
