✝ Unless otherwise specified, data found in the “Typ.” column is at T_A = 25°C and V_DD = 3.0V. These parameters are not tested and are for design guidance only. Note: Settling time is 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 resistive loads connected to ground. If the DAC output needs to sink current, it is recommended to increase the sinking capability by placing a suitable resistor between the DAC output pin and ground.
