What is the main reason of producing noise from hinge pin?

  Hinge pin out from the sample and hold circuit LF398H composition of such detection circuit. It maintained on the storage capacitor C analog signal peak voltage Vm. To quickly follow changes in input voltage Vin, the hold capacitor C should be relatively reduced capacity.

  The relative decrease of C, will result in maintaining voltage, the output voltage Vout of the decline rate to accelerate. These two contradictory is so that this circuit is difficult to achieve high performance.

  It consists of A / D conversion section and the digital voltage peak detector components, the interface circuit includes a microprocessor, is responsible for data communication with the computer and receive control signals from the computer, and control detection system work.
 

Steel shaft,axle shaft and motor shaft which are producted by the professional manufacturer and exporter Fenghua Zhaoxu Micro Shaft Co., Ltd. are sold at home and overseas.
