Page 3: Device Information
The USB connection generates a 5V supply for the EVM. The onboard controller generates 3.3V of power for the input/output (IO) signals generated by the onboard controller. These IO signals are level translated to the IO supply voltage (VIO) of the AMC8V208. An onboard voltage regulator generates 1.8V for use as the AMC8V208 IO supply voltage. - Page 4 4.99Ω load resistor to measure the 3-4 open: IDAC1+ output disconnected from resistor current as a function of the voltage. 4.99Ω load resistor.
