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.
The REFTS and REFBS voltages set the analog input span limits FS+ and FS respectively. Any voltages at
AIN greater than REFTS or less than REFBS will cause ADC over-range, which is signaled by OVR going high
when the conversion result is output.
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.
