5. Output level is dependent on the voltage on VREF, the value of RSET, and the load.
6. Test performed with C
7. The supply voltage rejection is the relative variation of the full-scale output driving a 37.5 load for a 5% supply variation:
8. If using an external voltage reference, it is not powered down. The internal voltage reference is powered down.
