✝ Data found in the “Typ.” column is at T_A = 25°C and V_DD = 3.0V unless otherwise specified. These parameters are for design guidance only and are not tested. Note: Settling time measured while DAC.DATA[9:0] transitions from ‘`0x000`’ to ‘`0x3FF`’. The DAC output has a limited current sinking capability. It is 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 may sink current.
