Figure 18. ADC Reference Generation Mode = AVDD
Connecting MODE to AVDD enables the internal reference buffer. Its inputs are internally switched to the REFTS
and REFBS pins and its outputs internally switched to pins REFTF and REFBF. The internal connections
(REFTS to REFTF) and (REFBS to REFBF) are broken.
To match the signal span to the full ADC input span, the voltage difference between REFTS and REFBS should
be REFTS – REFBS = [(FS+) – (FS–)]
× Gain, with the average of the REFTS and REFBS voltages being the
AIN midscale voltage, VM.
Typically, REFSENSE is tied to AVDD to disable the ORG output to VREF (as in Figure 19), but the user can
choose to use the ORG output to VREF as either REFTS or REFBS.
