Hello!I need to use non inverting op amp in my project. I'm complete beginner and I've never used any op amp before. I didn't get expected results from op amp in a project so I decided to build simplest schematics I can think of so I could test it. Unfortunately, it still doesn't work. I need help, I really cannot understand what I'm doing wrong.So I used parts I had in home:-op amp lm2902n data sheet-22k resistor-12k resistors-arduino unoI made it that way:schematicsHere is how I understand this:Arduino sends 3.3V signal to op amp plus input. Op amp is powered by 9V battery. I connect one 22k resistor between minus input and output and three 12k resistors to the ground. So I think I should get output voltage of V2 = V1(1+22/36) = 4,5V. That signal is send to arduino analog input which should give me number close to 1000 as 1023 is 5V. I however get something around 60 and op amp is getting hot. I ask for help with understanding what I'm doing wrong.
That opamp cannot drive to the +ve rail. You are asking it to do so.
OP is powering it at 9V so 5.3V is comfortably below the rail.
