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

Note 1: Devices are 100% production tested at TA = +25°C. Limits over temperature are guaranteed by design.
Note 2: INL linearity is from code 48 to code 1023.
Note 3: Specification based on characterization data. Not production tested.
Note 4: Guaranteed by design. Not production tested.
Note 5: The DACs continue to operate at currents lower than 50A on the 1.2mA range and 150A 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 0A.
Note 6: Compliance voltage range is defined as the range where the output current is -2 LSB of its value at VOUT = +1V.
Note 7: Settling time is measured from 0.25 x full scale to 0.75 x full scale.
Note 8: The device draws higher supply current when the digital inputs are driven with voltages between (VDD - 0.5V) and (VGND +
0.5V). See Supply Current vs. Digital Input Voltage in the
Typical Operating Characteristics.
