2.2 Digital Interface

As noted in Section 1, the ADS7038Q1EVM interfaces with the PAMBoard, which in turn communicates with the computer over the USB. The two devices on the EVM that communicate over SPI are the ADS7038-Q1 ADC (U3) and the electrically erasable programmable read-only memory (EEPROM) (U4). The EEPROM is preprogrammed with the information required to configure and initialize the ADS7038 platform. Once the hardware is initialized, the EEPROM is no longer used.
