Looking for onewire interface ADCs and I/O expanders

Rob Helvestine1

Hello. I am designing a daughterboard that has to take ADC measurements and IO measurements. The interface to this daughterboard is a one wire interface - not SPI, I2C, etc. Does TI sell ADCs, I/O expanders, and external DACs that have a one-wire interface? I'm trying to avoid a one-wire to I2C translation on this board, and strictly use one wire interface parts.

Thanks,

Rob

Hello Rob,

We do not have One Wire Interface ADC's. The best device for your application is the TLA2528, which is I2C and has 8 optional GPIOs

Rob,

Unfortunately we do not have any one-wire IO expanders, the only devices we have in the INT TRX portfolio would be our I2C expanders which require two wires for communication.
