I have to build a non-inverting amplifier which has a gain of approximately 250 using an LM358.
The values for my resistors are:
Rf = 50.4 kΩ
Rg = 201 Ω
Therefore, I have a gain of approximately 251.7. I am sending a 5V output from an arduino to a voltage divider which makes the new Vout = 0.005V. I am then sending the 0.005V to the non-inverting input of my LM358. The power supply for my chip is a 8.75V battery. Whenever I check the Vout from my LM358 I am getting .95V when I should be getting approximately 1.25-1.26V. Any suggestions on what I have done wrong?
