1 Temperature range (A, B versions): 40°C to +105°C; typical at +25°C.
2 See the Terminology section.
3 DC specifications tested with the outputs unloaded.
4 Linearity is tested using a reduced code range: AD5306 (Code 8 to 255); AD5316 (Code 28 to 1023); AD5326 (Code 115 to 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, the offset error must be negative; for the amplifier output to reach its maximum voltage, VREF = VDD,
the offset plus gain error must be positive.
8 Interface inactive; all DACs active. DAC outputs unloaded.
