However, I measure 1 to 8 mA current in both + and - pins of the IC.
The manufacturer doesn't quote a maximum current at the TL082 input pins but as they are direct connections to the gates of JFETs, I'm pretty sure you are measuring wrongly or your op-amp is fried.
Brian.
Those are voltages, your post title and first message say input currents. To measure the current you must break the connection at pins 2 & 3, one at a time, and connect the test meter across the break.
Brian.
Of course there is. What about transistors Q6 and Q16?.............
It is a simple KCL. There is no way for current except pin 2 of the op-amp.
I'm pretty sure you are measuring wrongly or your op-amp is fried.
No. Consider the negative voltage setting.Your schematic has the V5 polarity connected backwards.
Of course I saw that.No. Consider the negative voltage setting.
There's nothing wrong with this, and it's not the software but the user who decided to draw the schematic this way. It may be more intuitive to set the voltage to +15 and connect the negative voltage source terminal to the negative OP supply pin. Both ways result in supplying the OP correctly.Of course I saw that.
Why does the stupid SIM software wrongly show the positive terminal of the battery at -15V?? If somebody is wiring it then they must guess which is correct??
