Category: Converter Circuits / Voltage to Current Views: 1652 Rank: 0 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 visit page. You typically set R1 equal to R2.

Related circuits Figure 1 shows a classic voltage-to-current (V/I) converter. You can select the resistor values such that the output current in the load, RL, varies only with the input voltage, VIN, and is independent of RL. The circuit is widely used in industrial instruments for supplying a 4- to 20-mA signal.... The current out is Iqut—Vin/R. For negative currents, a PNP can be used and, for better accuracy,-a Darlington pair can be substituted for the transistor. With careful design, this circuit can be used to control currents of many amps A simple voltage-to-current converter is shown in the figure. The current out is 0t or Vjn/R.

Voltage-to-current converter drives white LEDs You sometimes need to drive a white LED from one 1.5V battery. Unfortunately, the forward voltage of a white LED is 3 to 4V. So, you would need a dc/dc converter to drive the LED from one battery. Using the simple circuit in Figure 1, you can drive one white LED or two series-connected green...
