NOTES:
5. Output level is dependent on the voltage on VREF, the value of RSET, and the load.
6. Test performed with C
L
= 40pF, I
O
=
±
2mA, V
IH
= 3.0V, V
IL
= 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 37.5
load for a
±
5% supply variation:
PSRR = 20 x log (
V
AA
/
V
OUT
).
8. If using an external voltage reference, it is not powered down. The internal voltage reference is powered down.
