NOTES
1
See Terminology section.
2
Temperature range: B Version: –40°C to +105°C; typical specifications are at 25°C.
3
Linearity is tested using a reduced code range: AD5332 (Code 8 to 255); AD5333 (Code 28 to 1023); AD5342/AD5343 (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
In order for the amplifier output to reach its minimum voltage, Offset Error must be negative. In order for the amplifier output to reach its maximum voltage, V
REF
= V
DD
and
“Offset plus Gain” Error must be positive.
