Hi all,
I´m currently looking for a way to replace the pots on an SSL EQ (currently I have a 82e132 board here) with digital pots.
I have already tinkered around with an Arduino and have the digital Midi control side down.
For a digital pot I recently found and ordered this part to try out:
https://www.microchip.com/wwwproducts/en/MCP45HV51
http://ww1.microchip.com/downloads/en/DeviceDoc/20005304A.pdf
It allows for an high analog voltage of +-18dB.
My question at the moment is if the current rating of the part is high enough:
- 12.5 mA (for 10 kOhm)
- 6.5 mA (for 50 kOhm and 100 kOhm)
Does anybody have knowledge of how much current flows through the pots of an SSL EQ?
Or a way of how I could find it out?
Thanks,
Christian
