Hi All:

  I'm making an application sending command via RS-485 to a
microprocessor using DAC to send Voltage signal, ADC to receive
feedback signal.
 
  I've found some 51 families have both DAC and ADC on one chip. But I
‘ll need other chips to be the RS-485 interface.

  Is there any microcontroller containing RS-485 interface and more
than 2 8bits ADC and a DAC (4bits or more will do the job) in one
signal chips

Thanks

For Rs-485 you should use 75176 for converting TTL levels (UART)
to RS485.

No.
Best to use a seperate chip for RS-485 (=cheap chip). Like that, if it
gets 'zapped' you don't kill the micro (=expensive chip).

Or properly protect it so it doesn't ever get zapped.

I appologize for this reply so do not take it as offensive.

Dejan, where are you from, Croatia?
