1 The max/min specifications are guaranteed over this range. The max/min values are typical over 3.0 V to 3.6 V.

2 Temperature range TMIN to TMAX: –40°C to +85°C.

3 Guaranteed by characterization.

4 Full drive into 37.5 Ω load.

5 DACs can output 35 mA typically at 3.3 V (RSET = 150 Ω and RL = 37.5 Ω), optimum performance obtained at 18 mA DAC current (RSET = 300 Ω and RL = 75 Ω).

6 Minimum drive current (used with buffered/scaled output load).

7 Power measurements are taken with clock frequency = 27 MHz. Max TJ = 110°C.

8 IDAC is the total current (min corresponds to 5 mA output per DAC, max corresponds to 37 mA output per DAC) to drive all three DACs. Turning off individual DACs

reduces IDAC correspondingly.

9 ICCT (circuit current) is the continuous current required to drive the device.

10 Total DAC current in sleep mode.

11 Total continuous current during sleep mode.
