Voltage-to-current converter

Posted on Aug 22, 2012

The voltage-to-current converter in Figure 1 can both source and sink current. The circuit is more flexible than some traditional current references that require different topologies for current sourcing and sinking. Also, you can easily adjust the value of the current reference by simply adjusting the circuit`s input voltage.

You typically set R1 equal to R2. The output current is a function of R3 and the gain of the instrumentation amplifier. Note that capacitor C1 stabilizes the circuit. In this example, R3=10 M, and the instrumentation amplifier`s gain is uni
