11.2 System reference and power management
11.2.1 Internal/external reference
The ADC1213D 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 pin VREF and
SENSE (see Figure 11 to Figure 14), in 1 dB steps between 0 dB and
6 dB, via SPI
control bits INTREF[2:0] (when bit INTREF_EN = logic 1; see Table 21). The equivalent
reference circuit is shown in Figure 10. An external reference is also possible by providing
a voltage on pin VREF as described in Figure 13.
If bit INTREF_EN is set to logic 0, the reference voltage is determined either internally or
externally as detailed in Table 10.
