Conditions/Comments

DACs active and excluding load currents. Unbuffered

Reference, VIH = VDD, VIL = GND

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.

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.
