>Second, he has made a common mistake that many designers interfacing to current output DACs make. He thinks in terms of voltage rather than current. You must think in terms of current when you interface with a current output DAC. Look at the current loop between the Idac and analog ground and what do you see? A resistor and a battery.The secret to designing a good I/V converter is to put as little garbage as possible in the current loop.<
