I'm looking for a uC with three or four 12 bit DACs. It has to be cheap too. The only other requirement is that it needs to have I2C for control.
The least expensive approach I've come-up with so far is to use a Maxim (or similar) 12 bit quad DAC chip via SPI I'd then drive it with a small dirt-cheap uC with SPI and use the I2C port to talk to the outside world.
Any ideas?
