Op-Amp: Voltage to Current Converter

In this video, how to design the voltage to current converter circuit using op-amp has been discussed. Why Voltage to Current Conversion? Many times in the industrial applications it is required to transport the voltage from one location (from a sensor) to the other location (Data Acquisition System). During the transportation, the voltage used to get dropped across the cable and at the other end output voltage used to be lower than the actual voltage. This problem can be avoided by using the voltage to current converter. The current will remain constant throughout the cable length and it is less prone to the external noise. Apart from that in many lab experiments, for testing many circuit components this voltage to current converter circuit is very useful. These type of current sources are also known as the voltage controlled current source. Because the output current can be controlled by changing the input voltage. Application of Voltage to Current Converter: 1) Testing the circuit components (Diode, Zener Diode) 2) Driving the LEDs 3) To convert the sensor voltage into the current (4-20 mA) in industrial applications. The timestamps for the different topics covered in the video is given below: 0:25 Why Voltage to Current Conversion? 2:32 Passive Voltage to Current Converter and it's limitation 3:27 Floating load Voltage to Current Converter using Op-amp 4:46 Voltage to Current Converter Applications 5:50 Grounded Load Voltage to Current Converter using Op-amp This video will be helpful to all students of science and engineering in understanding how to design the voltage to current converter using the op-amp.
