Notes

  • 1.

    All VDD and VSS connections must be made to the same power supply.

  • 2.

    Equivalent to discharging a 100 pF capacitor via a 1.5 kΩ series resistor.

  • 3.

    Equivalent to discharging a 200 pF capacitor via a 2.5 μH series inductor.

  • 4.

    DAC operation cannot be guaranteed after a short-circuit has occurred.
