I want to use my Arduino Duemillanove to draw on an XY oscilloscope. I need to power two DACs from one Arduino. Any reccomendations?
LTC1660?
Inexpensive and has two DAC's in one package.

The Gadget Shield: accelerometer, RGB LED, IR transmit/receive, light sensor, potentiometers, pushbuttons
Rugged circuits prob has the best solution.
Or you could just use an R,2R ladder. Depends what resolution you need really.
I ordered one of the LTC1660s. It's not two, but eight DACs in one chip. That'll do just fine for my purposes!
