3.1.1 Theory of Operation

Figure 3-1 shows a simplified schematic of the DAC53701EVM board. There are two 16-pin connectors that provide access to all of the DAC pins. The GPIO, and I2C signals from the onboard controller are connected to the DAC through two level translators. Each level translator can be independently disabled to disconnect the onboard controller GPIO, and I2C, signals from the DAC signals while the DAC is running in stand-alone mode.
