1 The min/max specifications are guaranteed over this range. The min/max values are typical over 4.75 V to 5.25 V.
2 Ambient temperature range TMIN to TMAX: 40°C to +85°C. The die temperature, TJ, must always be kept below 110°C.
3 Full drive into 37.5 Ω doubly terminated load.
4 Minimum drive current (used with buffered/scaled output load).
5 Power measurements are taken with clock frequency = 27 MHz. Max TJ = 110°C.
6 IDAC is the total current (min corresponds to 5 mA output per DAC; max corresponds to 37 mA output per DAC) to drive all four DACs. Turning off individual DACs
reduces IDAC correspondingly.
7 ICCT (circuit current) is the continuous current required to drive the device.
8 Total DAC current in sleep mode.
9 Total continuous current during sleep mode.
