You can essentially do that already with the SSI2130/SSI2131 by
holding the TCAP pin at ground, for example an inverting opamp which
would give you an output voltage that is the exponential of the CV.

There are boutique distributors that have some of these new and newly remade parts, but none that I've seen carrying a manufacturer's whole line. I'd email the manufacturer but I doubt I could afford the MOQ, and I'd rather not become a boutique reseller myself. I see ebay has sellers of the AS3340 and such, but not the AS3341.

Several resellers of the SSI product line:
