1 The min/max specifications are guaranteed over this range. The min/max values are typical over 3.0 V to 3.6 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 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 38 mA output per DAC) to drive all four 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.
