Re: Digital to Analog Converters

Why not just use one of Analog's serial input quad DACs and bitbang the outputs? you could probably get a quad dac working faster that way than writing your own I2C stuff (unless you're already odne this, in which case its a moot point..)

Do you think this will get the job done? Are there any special characteristics that I should be looking for?

Re: Digital to Analog Converters

that looks good. SPI is a plus, as PICs have SPI support built in (usually).. 8 bit quads are good since the OI is 8 bit (last I remember anyway) what you picked seems ideal to me. PM me if you have any problems.
