11.3.1 Internal/external references
11.3 System reference and power management
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
The equivalent reference circuit is shown in
possible by providing a voltage on pin VREF as described in
