An op amp is shown buffering Vref and not using it. But the op amp is going to be doing something else later... Temporary schematic. I...

No. The clipping diodes are clipping at voltages that surround vref by 0.6v (depending on choice of diode). Vref is not relevant to the...

Yes, but I believe @thunderaxe is planning to use that extra opamp for something else eventually. And in this particular, simple...

Could also save a component and do this...

And, the sour grape has a vref supply and then doesn't use it as the reference to the first op amp???

The sour grape has a vref buffer and doesn't use it! The output of this opamp is a perfect Vref supply to the rest of the circuit. And...

I prefer to finish it as fast as possible, very late at night if possible, get the order in so that production "starts", then the next...

I ordered 5 more of the same item and they all have 32 pins. Caveat emptor, of course.

Show me a schematic...

It could be used to buffer the bias voltage, too.

YES YES - and *please* make them just a *tiny* bit smaller to fit a 1590b. All of my projects I've managed to shoehorn the 125B pcbs...

I wanted to take a moment to give everyone an update about the Spin FV-1 IC situation... Regretfully I've decided that as we move into...

And a reminder to folks new to this thread... These need a good preamp to make a pedal board amp. I have PCBs to do this and I suggest...

Those are selling for 99 cents right now at Ali to new subscribers. Hint, hint, to folks who want some... And only 2 bucks for for those...
