Figure 15. ADC Reference Generation, MODE = AVDD/2
When MODE = AVDD/2, the internal reference buffer is enabled, its outputs internally switched to REFTF and
REFBF and inputs internally switched to VREF and AGND as shown in Figure 15. The REFTF and REFBF
voltages are centered on AVDD/2 by the internal reference buffer and the voltage difference between REFTF
and REFBF equals the voltage at VREF. The internal REFTS to REFBS and REFTF to REFBF switches are
open in this mode, allowing REFTS and REFBS to form the AIN– to the sample and hold.
Depending on the connection of the REFSENSE pin, the voltage on VREF may be externally driven, or set to
an internally generated voltage of 1 V, 2 V, or an intermediate voltage (see the onboard reference generator
configuration).
