I am trying to get a handle on what the parts landscape is like
now for cost-effective CV control. Back in 2017 the lm13700 was
really the only available OTA . I was just starting to work with
the ssm2164 at the time but never used it extensively.</div>

<p>It may just be my opinion, but...why <i>not</i> go with what you
know?<br>

<p>LM13700(M) is still in production by TI and not expensive in
quantity -- cheaper than the other options you mention. TI
themselves will even sell them to you, e.g. 100 @ US$0.741 each.
Coolaudio (Behringer)'s V13700 is about about the same price,
~US$0.92. Compare with SSI2140 at e.g. $2.79 each in that
quantity.<br>

<p>Since this is DFM, I'm going to assume SOIC / SSOP / etc. vs. DIP
is not an obstruction for you.<br>

<p>Can't go wrong with the SSI2140 though, or the V2044A, or even
the AS2164/33x0 devices -- assuming the increased BOM cost is
justified by the advantages of the new devices, and you're not
trying to colour outside the lines that they draw.<br>
