Data in the “Typ.” column is at TA = 25°C and VDD = 3.0V unless otherwise specified. These parameters are for design guidance only and are not tested.

Note:
  1. Settling time measured while DAC.DATA[9:0] transitions from ‘0x000’ to ‘0x3FF’.
  2. The DAC output has a limited current sinking capability designed to drive against resistive loads connected to ground. It is recommended to increase the sinking capability by placing a suitable resistor between the DAC output pin and ground if the DAC peripheral sinks current.
