Surely you just use the more modern more integrated designs. They will be more accurate and use less board space. </div>

I'm sure Neil J can pipe in here with exact figures on how much more accurate they are.</div>

imagine someone asked you to make some new synth modules.</div>

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>

In the interim I have built synth circuits but only in quantities of one where cost was no object and I was able to rely on my own extensive parts supply. </div>

So my question is this-- if I am thinking about design for manufacturing<span class="x__Entity x__EType_OWA_HYPHEN x__EId_OWA_HYPHEN_1 x__EReadonly_1" style="display:inline-block"><span id="x_hyphen2" class="x_hyphen">—</span></span>what do you think the best

Has anyone tried the quad ALFA OTA? Is it even readily available? Same for the new SSM2040. </div>

OR would you just use the 2164 instead? </div>

OR would you just try to make discrete OTAS out of say the BCM856DS //BCM847BS</div>
