NOTES

1See Terminology section.

2Temperature range: B Version: –40

°C to +105°C; typical speciﬁcations are at 25°C.

3Linearity is tested using a reduced code range: AD5332 (Code 8 to 255); AD5333 (Code 28 to 1023); AD5342/AD5343 (Code 115 to 4095).

4DC speciﬁcations tested with outputs unloaded.

5This corresponds to x codes. x = Deadband voltage/LSB size.

6Guaranteed by design and characterization, not production tested.

7In 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 = VDD and

“Offset plus Gain” Error must be positive.

Speciﬁcations subject to change without notice.
