Conditions/Comments
VDD = 5 V
VDD = 3 V
Coming out of power-down
mode, VDD = 5 V
Coming out of power-down
mode, VDD = 3 V
VDD = 5 V ± 10%
VDD = 3 V ± 10%
VDD = 2.5 V
VDD = 2.5 V to 5.5 V, TTL and
CMOS compatible
VIH = VDD and VIL = GND
All DACs in unbuffered
mode, in buffered mode
Extra current is typically x μA
per DAC; x = (5 μA +
VREF/RDAC)/4
VIH = VDD and VIL = GND
1 Temperature range (A, B version): −40°C to +125°C; typical at 25°C.
2 See the Terminology section.
3 DC specifications tested with the outputs unloaded unless stated otherwise.
4 Linearity is tested using a reduced code range: AD5308 (Code 8 to Code 255), AD5318 (Code 28 to Code 1023), and AD5328 (Code 115 to Code 4095).
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.
8 Interface inactive. All DACs active. DAC outputs unloaded.
9 All eight DACs powered down.
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.
