Note 1: All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Note 2: Guaranteed monotonic.
Note 3: Gain error is defined as:
where VF0,Meas is the DAC voltage with input code F0 hex and VF0,Ideal is the ideal DAC voltage with input code F0 hex or
(VREFH - VREFL) x (240 / 256) + VREFL.
Note 4: The device draws higher supply current when the digital inputs are driven with voltages between (VDD - 0.5V) and (GND +
0.5V). See Supply Current vs. Digital Input Voltage in the Typical Operating Characteristics.
Note 5: Output settling time is measured from the 50% point of the rising edge of the last SCL of the data byte to 0.5 LSB of OUT_’s
final value for a code transition from 10 hex to F0 hex.
Note 6: Crosstalk is defined as the coupling from a DAC switching from code 00 hex to code FF hex to any other DAC that is in a
steady state at code 00 hex.
Note 7: Reference feedthrough is defined as the coupling from one driven reference with input code = FF hex to any other DAC out-
put with the reference of the DAC at a constant value and input code = 00 hex.
Note 8: SCL clock period includes rise and fall times tR and tF. All digital input signals are specified with tR = tF = 2ns and timed
from a voltage level of (VIL + VIH) / 2.
Note 9: An appropriate bus pullup resistance must be selected depending on board capacitance. Refer to the document linked to
this web address: www.semiconductors.philips.com/acrobat/literature/9398/39340011.pdf.
Note 10:The busy time begins from the initiation of the stop pulse.
