ADC/DAC

[Dirk Bruere at Neopax]

Any recommendations for a cheap combo chip, 12 bits min, for interfacing to a
uP? Ideally I need single 5V rail supply and conversion rate of around 100K/s
for the ADC

Why not us a micro with built in ADC such as one of the Analog Devices
microcontrollers

Largely because I need a CANBUS i/f, and that means PIC unless someone can point
me to some extremely cheap ucontrollers with CANBUS and 12 ADC/DAC

If not, you could drop a MCP2515 SPI<->CAN onto whichever micro you
want.

One reason for using the PIC is the wealth of free code available, probably
unmatched by any other ucontroller.

Certainly in quality. ;-)

But even if the drivers are a major factor, you may *still* find it
cheaper to use two micros and relegate the 805x to just buffering the
information to and from the ADC/DAC.

Why, just for once, can't I find the perfect part to do the job? Everything I've
done for the last 25yrs has been a balancing act...

Eventually it catches up with you. You and your little dog too.

How about something like a dspic30F6011A, just add a DAC.

Possible, but it seems a bit overkill, esp the pin count.

30F4013 then, whatever. ;-)

Austria Microsystems has a series SPI based 12bit ADC.
