1.3 Specification

Figure 5-3 shows the block diagram of the DAC81404EVM board. By default, the DAC81404EVM connects to a local machine USB port through a USB-A to micro-USB cable.

The USB provides the 5-V default VDD supply to the DAC81404. Voltage regulators generate 3.3-V and 1.8-V from USB 5 V supply. These 3.3 V and 1.8 V supplies are used to power the FTDI controller, level shifter, and IOVDD of DAC81404. IOVDD can be 3.3-V or 1.8-V depending on the jumper J5 setting. DVDD and IOVDD device supply inputs for the DAC81404 can be externally supplied through banana jacks. The AVDD and AVSS need external supply connections as well.
