Alright, I've got this homework problem that I cannot figure out for the life of me, I'm terrible at electronics so any help is much appreciated!
The problem is stated as follows:
Develop a schematic of a single stage opamp amplifier based on the LM324 chip. Note that LM324 chip has four opamps, use just one. The opamp is to have a single supply voltage of 5 volts and operate in an inverted configuration. The input resistance must be at least 1k ohm and the gain must be 10. The output should be 2.5 volts at 0 volts input.
I understand that the gain of 10 is achieved by having the feedback resistor 10 times that of the input resistor, right?
I'm not familiar with the LM324 chip so throwing that into the mix confuses me even more!
Also, how do I get a 2.5 volt output with a 0 volt input?! I DON'T UNDERSTAND! I thought 0 input was 0 output!
Thanks for any help!
