11.3 System reference and power management
11.3.1
Internal/external references
The ADC1112D125 has a stable and accurate built-in internal reference voltage to adjust
the ADC full-scale. This reference voltage can be set internally via SPI or with pins VREF
and SENSE (programmable in 1 dB steps between 0 dB and
6 dB via control bits
INTREF[2:0] when bit INTREF_EN = logic 1; see
Table 23
). See
Figure 21
to
Figure 24
.
The equivalent reference circuit is shown in
Figure 20
. An external reference is also
possible by providing a voltage on pin VREF as described in
Figure 23
.
