A | Page 4 of 28 Parameter1 B Version2 Unit Conditions/Comments Min Typ Max POWER REQUIREMENTS VDD 2.5 5.5 V IDD (Normal Mode) DACs active and excluding load currents. Unbuffered VDD = 4.5 V to 5.5 V 140 250 μA Reference, VIH = VDD, VIL = GND VDD = 2.5 V to 3.6 V 115 200 μA IDD increases by 50 μA at VREF > VDD − 100 mV. In buffered mode, extra current is (5 + VREF/RDAC) μA, where RDAC is the resistance of the resistor string. IDD (Power-Down Mode) VDD = 4.5 V to 5.5 V 0.2 1 μA VDD = 2.5 V to 3.6 V 0.08 1 μA 1 See the Terminology section. 2 Temperature range: B Version: −40°C to +105°C; typical specifications are at 25°C. 3 Linearity is tested using a reduced code range: AD5330 (Code 8 to Code 255); AD5331 (Code 28 to Code 1023); AD5340/AD5341 (Code 115 to Code 4095). 4 DC specifications tested with output unloaded. 5 This corresponds to x codes. x = deadband voltage/LSB size. 6 Guaranteed by design and characterization, not production tested. 7 For the amplifier output to reach its minimum voltage, offset error must be negative. For the amplifier output to reach its maximum voltage, VREF = VDD and offset plus gain error must be positive. AC CHARACTERISTICS1 VDD = 2.5 V to 5.5 V. RL = 2 kΩ to GND, CL = 200 pF to GND; all specifications TMIN to TMAX, unless otherwise noted. Table 2.
