Dual 12-bit ADC: CMOS or LVDS DDR digital outputs
If bit INTREF_EN is set to logic 0, the reference voltage is determined either internally or
externally as detailed in
Table 12
.
Table 12.
Selection
[1]
The voltage on pin VREF is doubled internally to generate the internal reference voltage.
Figure 21

illustrate how to connect the SENSE and VREF pins to select the
required reference voltage source.
