Re: DPOTs for audio control
Yes. VCA, SPI interface for control, stored wiper (gain) setting, slewing between steps with an external C to eliminate zipping. Add an analog Ec for realtime control. The VCA always wakes up with the last gain setting and moves between steps with a smooth linear dB slope. I didn't literally mean a...

Re: DPOTs for audio control
Well, in the 5171 the zip performance is quite good. I also recall the MDAC LogDACs being fairly smooth too. With most program material the small step changes get masked. In any switch-based solution however (except maybe PWM) there will always be a step response to gain change. That's why I think t...

Re: DPOTs for audio control
Yeah no need for people to keep exploring them when they glitch.
But hey I tried to get you to show your hand.

Re: DPOTs for audio control
Kinda thought that's what you'd say.I am not comfortable sharing details of what I am doing, since it is in a commercial design so proprietary.

Re: DPOTs for audio control
VCAs. With a NVM DPOT on Ec.
Holy shit.
Holy shit.

Re: DPOTs for audio control
Thanks for posting this John. I know that in your application that the ADI LOGDACs might be too expensive. They also zip but IIRC are monotonic in their gain steps. Have you ever tried them and is ADI still in production of these? I remember them being used in the Studer 820 and MCI/Sony APR-24.

Re: automatic timing in compressor confusion
In your second try using the NLC you mention a 10K resistor. Where was that in the circuit?
