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