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.

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.
