I've been trying to setup this op amp for the past couple of hours, and I can't seem to do it successfully. I have a single supply, so I created a voltage divider with resistors to get +ve and -ve. I made the connections based on the data sheet by Texas Instruments. After that, I tried adjusting the offset null, but no luck.

Then I said okay, I'll try my circuit in LTSpice. The LTSpice model perfectly matches the inverting amplifier circuit. I re-checked my circuit and matched the model. Still the output voltage is off (~0.15V). I also tried other op amps and they give me approximately the same results. What am I doing wrong?

AFTER TWO DAYS I FINALLY GOT IT TO WORK

So I believe my issue was that the voltage divider wasn't a true voltage divider because whenever I hooked up my circuit the divider was not splitting the voltage evenly. So I decided to use a voltage follower and use its high impedance to my advantage. Needless to say, it worked! I think I also had grounding issues with my signal. Oh, and I also switched my opamps to the TL051IP since the previous didn't seem to provide accurate results. Anyway, this is the schematic for a NoninvertingInverting Amplifier with a Single Power Supply! I labeled the V+, V-, and VG for convenience since this tripped me up the most for some reason.
