OUTPUT OFFSET VOLTAGES
External offset voltages from 0 mv to 800 mV `above the DAC' can be added for the V
Offset is set by a resistor divider from V
factors change by the same amount:
For example: For 0 V offset: pin voltage = GND; For 800 mV offset: pin voltage = V
The input to the OFFSET pin for the VDD output is encoded by an internal ADC.
The input to the NB_OFFSET pin for the VDDNB output is encoded by the same ADC.
The reference for this ADC is VCC. The ADC's output is ratiometric to VCC.
Voffset IN represents the voltage applied to the OFFSET or NB_OFFSET pin.
It is intended that these voltages be derived by a resistive divider from Vcc.
The recommended total driving impedance is <10 kilohms.
