Don’t waste your time designing and/or packaging a Constant Current output OpAmp or Voltage to Current Conversion amplfier circuit for your application. Utilize one of our self contained Ready Modules for  your application or simply use in conjunction with a basic Multimeter as an inexpensive alternative to an expensive Constant Current Source / Sink.


  • Precision Linear Adjustable Bipolar Constant Current Source / Sink Output Module
  • Accuracy:
    a.) Full scale accuracy typically better than 0.1%
    b.) High Voltage module(s) full scale accuracy better than 0.3%
  • Converts from input voltage to output constant current.
  • Current Output Control:
    a.) Option#1: ±10V input relative to applicable module full range current out.
    b.) Option#2: Manual Trim-Potentiometer adjustment .
  • Maximum Load Voltage / Output Compliance Load Voltage:
    a.) Standard small signal Module ... ±12V
    b.) High Load Voltage small signal modules up to ±180V
    c.) High Current modules up to ±36V

We Recommend our GROUNDED LOAD modules for most all applications. For High Current modules the maximum Load voltage is typically
 4-5V less than applied by the external Bipolar power supply.
