SBAU352 June 2020 ADS131B04-Q1
As noted in Section 1, the EVM interfaces with the PHI and communicates with the computer over the USB. There are two devices on the EVM with which the PHI communicates: the ADS131B04-Q1 ADC (over SPI) and the EEPROM (over I2C). The EEPROM comes pre-programmed with the information required to configure and initialize the ADS131B04-Q1EVM platform. When the hardware is initialized, the EEPROM is no longer used.
