i want to design a simple current to voltage converter. Is there any basic idea and components that can help me to construct a I to V converter? Please assist me..
Data, data! We need DATA! ......... Exactly what do you want to do? What is the starting situation and what is the desired result? How much current? What output voltage is required? What is the current source? etc, etc.
Voltage = Current x Resistance, or E=IR
If 10mA (0.01 Ampere) flows through a 1 Ohm resistor, you will measure 10mV across the resistor.
If 10mA flows through a 1,000 Ohm resistor, you will read 10v across the resistor.
If 10mA flows through an 0.1 Ohm resistor, you will read 1mV across the resistor.
I need to convert an input current (perhaps a range from microAmp to milliAmp) to a voltage in the range of 0-10V maximum. But at the same time the amount of input current must be proportional to my output voltage. For eg. 1mA = 1V output (this is only example). So can i just use an opamp like LM741 to make a current to voltage converter? If yes, how should be the circuit looks like?
Again, data is needed. What are you going to use the voltage for? DVM,, etc. The end use of the voltage makes a BIG difference. Your thought of an OP-Amp would provide buffering, and possible range change by providing amplification. Sgt. Wookie's table would get you started. What level of understanding do you have of Ohm's Law?
