I want to use OPA541 as a buffer simply to provide more current on the output. On simulation level everything works fine, any way the circuit is simple enough. Recently I bought an OPA541 and try to build everything but the circuit simply doesn't work as expected. Attached you can find the circuit topology. As input I used a square wave at 1kHz with vpp 4 V (0-4V) and connect the output directly to the osci. My output is a distorted signal which seems to oscillate up to V+ but it doesn't follow the input. I should say that no decoupling or other type of capacitor was used in this phase. Does anybody have an idea what is wrong?
