1 Temperature range TMIN to TMAX: –20°C to +85°C.

2 Guaranteed by characterization.

3 DACs can output 35 mA typically at 2.8 V (RSET = 150 Ω and RL = 37.5 Ω). Full drive into 37.5 Ω load.

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

5 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.

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

7 Total DAC current in sleep mode.

8 Total continuous current during sleep mode.
