Notes
1. Switching time measured from the 50% point of the EXTKEY transition edge to the 50% point of the selected analog
2. DAC output rise/fall time measured between the 10% and 90% points of full scale transition.
3. DAC settling time measured from the 50% point of full-scale transition to the output remaining within 1 LSB.
4. DAC analog output propagation delay measured from the 50% point of the rising edge of VCLK to the 50% point of
