Theory of Operation

Figure 3-1 shows a simplified schematic of the DAC63204EVM board. There are two 16-pin connectors that provide access to all of the DAC pins. The GPIO, I2C, and SPI signals from the onboard controller are connected to the DAC through three level translators. Each level translator can be independently disabled to disconnect the onboard controller GPIO, I2C, and SPI signals from the DAC signals while the DAC is running in stand-alone mode.
