4.1.4.1 ADC Configuration

Figure 5-5 shows the ADC Configuration tab that allows the user to quickly select the Reference range, enable the Reference buffer, VCM buffer, Auto Standby mode, Average mode, and to adjust the digital IO drive strength. Under the Waveform Settings, the Reference Voltage value can be updated if a different reference voltage is used from the default 2.5V EVM configuration. Please refer to the ADS127L18 data sheet for more details on the function of these settings.
