* The output impedance is a concern. Without the Output Buffer enabled, >100kohm impedance for the load is needed. Even WITH Output Buffer enabled, a 1kohm load is not really possible, both high and low end of range is not reached, which is a bit strange. 10kohm hasn't been tested yet, but datasheet indicates that a 5kohm load should be fine.
