Temperature range: B Version: –40°C to +105°C; typical specifications are at 25°C.
See Terminology section.
Linearity is tested using a reduced code range: AD5346 (Code 8 to 255); AD5347 (Code 28 to 1023); AD5348 (Code 115 to 4095).
DC specifications tested with outputs unloaded.
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
the offset plus gain error must be positive.
