Reference. VIH = VDD, VIL = GND.
IDD increases by 50 µA at VREF > VDD – 100 mV.
In Buffered Mode extra current is (5 + VREF/RDAC) µA,
where RDAC is the resistance of the resistor string.

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: AD5330 (Code 8 to 255); AD5331 (Code 28 to 1023); AD5340/AD5341 (Code 115 to 4095).
4DC specifications tested with output 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, VREF = VDD and
“Offset plus Gain” Error must be positive.
Specifications subject to change without notice.
