ADC solutions for real time parameter control?

[audionerd]

Hi all,

I am curious whether there are known/typical solutions to connect several (for instance 4) analog potentiometers to a VS1053 to control DSP parameters in real time; so with high resolution (10 bit/10kHz) and low latency.

Perhaps an ATTINY402 connected via UART could be used for this?

Thanks.

Inside our office? We would probably use VS1005 instead of VS1053...

Ah... does the VS1005 have inputs for connecting sensors like an analog potentiometer? I only see ADC inputs dedicated to audio on http://www.vlsi.fi/en/products/vs1005.html, or perhaps I'm overlooking something?

Yes, there is SAR AD converter (Successive AppRoximation), a few ch, 10 bits (or 12?)

Right, I see, I will look into that, I hadn't heard of SAR before. Thanks.
