Using The Gui To Control Adc2 - Texas Instruments ADS1263EVM-PDK User Manual

EVM Operation and GUI

7.6 Using the GUI to Control ADC2

As noted throughout this document, the ADS1263 includes two ADCs: a 32-bit primary device (ADC1), and
a 24-bit secondary converter (ADC2). The ADS1263EVM GUI is capable of controlling both ADC1 and ADC2
using the global settings on the left side of the GUI.
As Figure 7-7 shows, ADC2 can use a different data rate, gain, input channels, and reference voltage compared
to ADC1. However, ADC2 can only use the Sinc3 filter, and both ADCs must use the same number of Samples.
To view both ADC1 and ADC2 data in the GUI, select the Include ADC2 data? check box.
The GUI operates by converting samples at the data rate specified by ADC1, which can be different from ADC2.
Therefore:
• If the data rate for ADC2 is greater than the data rate for ADC1, some new samples for ADC2 are not
captured by the GUI. The GUI provides a warning when these conditions are met.
• If the data rate for ADC2 is less than the data rate for ADC1, repeat values are sampled for ADC2. These
values are not shown in the GUI such that ADC2 data is only updated when the data are new.
See the ADC2 section of the
from ADC2.
