Using DAC's with pics

Hello there,

and if so which would you recommend.

thanks again in advance John

Hi, John

I would recommend the one you really need !!! ...

let's stop joking : Which precision do you REALLY need ??? That's the only good question.

8 bits ( .4% ) ... using a full port with a R-2R ladder is enough !!!
( MAX 512 ... if really needed )
10 Bits ... (.1%)
12 bits ... (0.025 % ) ... best multimeters precision ...

LTC 1451,1257,1659
MCP 4921 from µChip

After that ... PCB drawing problems + tempco problems in sight !!!
