2.2.2.2 Level Translator (ADS111S02EVM and ADS111S04EVM)

Figure 2-4 shows the Texas Instruments TXB0104, a 4-bit bidirectional voltage-level shifter with auto direction sensing. The EVM uses the TXB0104 to translate voltage levels between the controller and the ADC. This translation decouples the ADC supply voltage from the controller I/O voltage so the user can power the EVM to enable higher input voltage measurements. For example, the user can set the ADC_VDD to 5V to measure larger signals while keeping the communication voltage (IO_VDD) at 3.3V
