2. Output level is dependent on the voltage on VREF, the value of RSET, and the load.
3. If using an external voltage reference, it is not powered down. The internal voltage reference is always powered down.
4. The supply voltage rejection is the relative variation of the full-scale output driving a 37.5 load for a 0.5% supply variation:
