NOTES:
5. Output level is dependent on the voltage on VREF, the value of RSET, and the load.
6. Test performed with CL= 40pF, IO = ± 2mA, VIH = 3.0V, VIL = 0.0V. Input reference level is 2.0V for all inputs.
7. The supply voltage rejection is the relative variation of the full-scale output driving a 37.5Ω load for a ±5% supply variation:
PSRR = 20 x log (∆VAA/∆VOUT).
8. If using an external voltage reference, it is not powered down. The internal voltage reference is powered down.
