Polysynth/Potmeters

[Guido Goebertus]

Hi list,

Has anybody ever tried these ones?

X9C103(R=10K)
X9C503(R=50K)
X9C104(R=100K)
 
These are digital controlled potmeters, 100 steps.
Audio In is (max) +/- 5V, 1mA.
Digital: Max. 2Mhz.
Eeprom on chip.

The pinout is:

1. INC
2. U/D
3. Vh
4. Vss
8. Vcc
7. CS
6. Vl
5. Vw

If they are current in/out or DC-in/out they might be extremely usefull (e.g. controlling ADSR times by a microcontroller, Vc mixer etc.)

Anyone ever used these ones?

BTW: We should do this polysynth, but we should *not* use VCO-chips like the CCM**** etc. We should use something like the FATMAN D/VCO. And we should use Tom G's Moogfilters. (IMO, that is:-)

Rgrds, Guido
