digi potenciometer

hello once again,

I'm looking for a digital potenciometer with about 10-20 taps, 10k-50k total value, Up/Down interface, easy to find and CHEAP.... any suggestions???... actually I'd like to control this D P with switches, so it has to be one with a simple U/D interface.... I've tried some from X*COR but the interface is not simple enough to use only switches...

regards,

digital potenciometer

I try the microchip MCP41010 and MCP42010 it are 10K and 256 taps, works very well!!

There are from Maxim too : see MAX5402

good luck :lol:
 

sorry for language

Dallas Semiconductor have the serie 18XX (1805,1802, 1803,....)
Try. it is facil

Log on to www.dalsemi.com. The Dallas semiconductors site has quite a huge varieties of digital pots that have a simple switch interface - like the DS1666.

Cheers

you can also make it yourself using analog signal switches and a counter which delivers a 'thermometer code'. The switches changes the input and feedback resistor of the opamp (so YOU can define the resolution), but of course it will be not that small as one single chip (but they're expansive)...
