An "analogue" DAC :-)

Lots of boutique jummies in that soup... Duelund, Sowter...

This really belongs in the Comrecial area of the forum... no?

It's a commercial product so by no way a schematics will be published.

It doesn't really look like an IV circuit! It seems like you use the DAC in the voltage mode (With an ESS DAC this reduces the the performance dramatically by the way).

If it is a commercial product, you should also make sure that safety requirements are met. This is not the case at the moment. There is no connection to safety Earth.

Exactly - now moved to the appropriate Vendor Forums sector.

Anyway, I'm sure you had your reasons, good luck with the new design
