ELECTRICAL CHARACTERISTICS (continued)
(V
DD
= +2.7 to +5.25V, GND = 0, external reference = +2.5V, output voltage = +2.0V, T
A
= -40°C to +85°C. Typical values are at
V
DD
= +3.0V, and T
A
= +25°C.) (Note 1)

Note 1:
Devices are 100% production tested at T
A
= +25°C. Limits over temperature are guaranteed by design.
Note 2:
INL linearity is from code 48 to code 1023.
Note 3:
Guaranteed by design. Not production tested.
Note 4:
The DACs continue to operate at currents lower than 50μA on the 1.2mA range and 150μA on the 3.6mA range. However,
performance is not guaranteed at these low currents. A code of all zeros has a nominal output current of 0μA.
Note 5:
Compliance voltage range is defined as the range where the output current is -2 LSB of its value at V
OUT
= +1V.
Note 6:
Settling time is measured from 0.25 x full scale to 0.75 x full scale.
Note 7:
The device draws higher supply current when the digital inputs are driven with voltages between (V
DD
- 0.5V) and (GND +
0.5V). See Supply Current vs. Digital Input Voltage in the
