2.7 EEPROM

Figure 2-7 shows the circuitry used with the EVM controller (PHI) for EVM identification. The EEPROM communicates with the PHI over an I2C bus and is not shared with the ADS131E08. This circuit is not required by the ADS131E08 for operation and is not powered when not used with the PHI.
