    Voltage follower enigma

    Thanks MrAl, but I would undestand better the problem, the LM358 datasheet say that this (like almost all) opamp can source but also sink current from out, so I don't undestand why I don't put load to 5V?... I can not change the load caracteristics, it is the internal contrast circuit of a 16x2...

    Voltage follower enigma

    Hi at all! This is my fist message. I'm testing a "not inverting voltage follower" with LM358 opamp: "Vin-" short whit "Vout" "Vss+" = 12V "Vss-"= 0V (Single supply) "Vin+" = [0; 5] V The load is a R0 = 22Kohm connected toward 5 V (i.e. not toward 0V). The problem is that when input...
