Hello, I have a question that I thought some of you may know an answer to.
I was recently testing an op amp is several closed-loop feedback configurations. Primarily inverting, and non-inverting.
When testing the output voltage of an invertin amplifier, I found that the output signal became attenuated at around 1.6MHz. The op-amp's data sheet says the bandwidth is 1.5MHz so this makes sense.
However, when I did the similar test with a non-inverting amplifier, I could only get up to 29KHz before bad deformation occurred. Why is this? I thought the op-amp was rated at 1.5MHz?
Does it have something to do with how many capacitors within the op-amp are being used in a non-inverting configuration?
I haven't been able to find a good answer so I will appreciate any help!
