Has anyone used the LTC1865 16 bit ADC 2 ch.
It is pin compatible to the LTC1298 which is half duplex 12 bit
The LTC1865 is full duplex.
Thank you for any help or suggestions.

    According to the datasheet the LTC1865 is a 16bit upgrade to the LTC1298.
    16-Bit Upgrade to 12-Bit LTC1286/LTC1298

    I think you are mistaken about half and full duplex. Both ICs use SPI/MICROWIRE™ Compatible Serial I/O and both ICs can have Dout and Din tied together if you want to use one IO pin.

    Anybody ever write a driver for this?

    Was hoping could just tweak the ltc1298 driver but look too different for that, even though pinout is the same…

  • You might want to look at the MCP3426. Already spin code out there for it.
