[HELP] asymmetric output op amp

[dbanner]

Why? For the simple reason of slew rate. For this reason, input bias current become important. The rail voltages are a secondary consideration.

i have test swap IC-2 NE5534 with OPA134, LME49710, AD847, same result,
I suspect it has something to do with 4066, later I will not use 4066, I will report the results again

do you have + and - power connected to the 4066's? You don't show it.

Also try removing the 4066 then measure 5534 output.

Have a look at the goldscan 5 schematic. Pretty straightforward. Like I said, input bias and slew go hand in hand.

this is my mistake, I don't use +5V and -5V on cd4066 ,

Thank for rickb, waltr, dbanner, green, moodz and KT315

Different supply 4093 and 4066, swing clipping,


After 4093 and 4066 supply with +5V / -5V


SOLVED,

Thanks All,

Good job.
