Note 1: Devices are 100% production tested at T
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,
Note 5: Compliance voltage range is defined as the range where the output current is -2 LSB of its value at V
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
