If you use your signal for regulation of something, ADC/DAC solution act like first order hold
https://en.wikipedia.org/wiki/First-order_hold
And it can cause instability in regulation.
So my advice would be OPAMP.

Circuit is not hard to make. You basically need 2 buffers and 1 compactor, few resistor, and that is it.
I can draw basic schematic, if you want...
