Looking for I2C based DAC recommenations

RobotWorkshop

I'm looking for a 2 channel DAC in DIP format that will connect to an I2C bus. 8-Bit or higher resolution would work. If there are any good 8-pin DIP devices for a single channel then a couple of those may work instead. Anyone have recommendations for parts that work well with the Propeller?

Google "i2c dac" ... you will get many results

It looks like my best option may be to start with either the MAX519 or the MX7543. Both of these have a pair of DAC's and the form factor is perfect. I'll try the MAX519 first since I think 8-bits will be fine enough resolution and this part is smaller and less expensive than the others.

BTW, nice i2c article with calcs at http://www.edn.com/article/521530-Design_calculations_for_robust_I2C_communications.php?cid=Newsletter+-+EDN+on+Embedded+Processing
