VCC=5V.
I am trying to condition 4-20mA analog signal.
I ma using a current sensing resistor of 47ohms to convert current to voltage.
at 4mA i get 188mV and at 20mA i get 940mV.
with a gain of 2.7, i must get 0.507Vand 2.53V at 4mA and 20mA resp.
but i get 0.3V and 0.6V as output.
I am not...
I am trying to test an temperature controller circuit(load). please suggest me something that will not reduce my output voltage and i could supply full 0-10v to the load.
VCC=12V.
I am feeding 12V into a voltage divider formed by an 200ohms resistor
and an 1K POT to vary the output of my vltg divider.
I am getting 0(some mV)-10V as per expectation at the vltg divider output.
I have further used an voltage follower ckt.
When i connect my load at vlg follower...
The amplifier works as a voltage follower. It takes 3.12V from the voltage divider, so it should give out 3.12V as it is an voltage follower but instead i am getting 1V. Can someone guide me on this..
