Temperature range (A, B version):
See the Terminology section.
DC specifications tested with the outputs unloaded unless stated otherwise.
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).
This corresponds to x codes. x = deadband voltage/LSB size.
Guaranteed by design and characterization; not production tested.
For the amplifier output to reach its minimum voltage, offset error must be negative. For the amplifier output to reach its maximum voltage, V
gain error must be positive.
Interface inactive. All DACs active. DAC outputs unloaded.
All eight DACs powered down.
Guaranteed by design and characterization; not production tested.
Temperature range (A, B version): –40°C to +125°C; typical at 25°C.
See the Terminology section.
