TPL0401A-10 Digital Potentiometer

[Wimax]

Hello Everybody !

Do any of you have experience with the TPL0401A-10 Digital Potentiometer on I2C bus ? I can't get it to work...

[Wimax]

The datasheet somehow misleads... the quick procedure for reading the internal register does not seem to work correctly, but the standard one seems to work.
The chip now accepts the programming and returns the correct value.

Hi Wimax
I see there was some code Les wrote for a Microchip Digital Pot, Maybe this will help.

MCP4551 anyone?

Hi Craig,

Thank you very much for the infos, fortunately I was able to get it working, it's a pity that for these devices the I2C addresses are all the same...you can only use one IC independently on the same bus.
