No internal connection
Reference Voltage input. Reference input range is 1V to 2.1V; programs the full-scale output voltage.
REFA = 2.048V for specified performance.

REFB = 2.048V for specified performance.
No Connect.
Reference Ground Return for the Reference Generator and Buffers.
This pin provides an output voltage proportional to temperature. The output voltage is 1.4V typical at
25°C die temperature; variation with temperature is 5mV/°C.
Determines the DAC Coding. This pin should be hardwired to either DVCC or DGND. When hardwired to
DVCC, input coding is offset binary. When hardwired to DGND, input coding is twos complement
(see Table 7).
