Digital Up/down Potentiometer

Hi all. A friend told me to ask in this forum…so here we go.

I’m going to build an Equalizer with digital Up/down Potentiometers instead of Faders. Therefore I found the AD5220 from Analog Devices. Where in germany can I buy this or a similar IC?

It should have:

128 taps or more

Supply Voltage doesn’t matter

100kOhm of resistance

Input signal should be Up/down and not 3- or 5.-wire

I found nothing at conrad, reichelt and elv

I’d be very glad if you could help me. Because if I don’t find the IC I’ll have to use normal Faders :cry:

Thx,

cosmo

hmm, not sure what’s happening there with the text, but the links do works…
