The max/min values are typical over 3.0 V to 3.6 V. 12Temperature range T MIN to TMAX: 0°C to +70°C. 13Guaranteed by characterization. 14Full drive into 37.5 Ω load. 15DACs can output 35 mA typically at 3.3 V (R SET = 150 Ω and RL = 37.5 Ω), optimum performance obtained at 18 mA DAC current (R SET = 300 Ω and RL = 75 Ω). 16Minimum drive current (used with buffered/scaled output load). 17Power measurements are taken with Clock Frequency = 27 MHz. Max T J = 110 °C. 18I DAC 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. 19I CCT (Circuit Current) is the continuous current required to drive the device. 10Total DAC current in Sleep Mode. 11Total continuous current during Sleep Mode. Specifications subject to change without notice. 3.3 V SPECIFICATIONS (V AA = +3.0 V – 3.6 V 1, V REF = 1.235 V, RSET = 150 . All specifications TMIN to TMAX 2 unless otherwise noted.) |
