POWER REQUIREMENTS
Note 1: Stresses beyond those listed under Absolute Maximum Ratings may
cause permanent damage to the device. Exposure to any Absolute Maximum
Rating condition for extended periods may affect device reliability and lifetime.
Note 2: All voltage values are with respect to GND.
Note 3: VCC = 4.5 to 5.5V unless otherwise specied.
VREF = REF+ – REF–, VREFCM = (REF+ + REF–)/2;
VIN = IN+ – IN–, VINCM = (IN+ + IN–)/2.
Note 4: fO pin tied to GND or to external conversion clock source with
fEOSC = 10MHz unless otherwise specied.
Note 5: Guaranteed by design, not subject to test.
Note 6: Integral nonlinearity is dened as the deviation of a code from a
straight line passing through the actual endpoints of the transfer curve.
The deviation is measured from the center of the quantization band.

The
l denotes the specications which apply over the full operating temperature
range, otherwise specications are at TA = 25°C. (Note 3)
TIMING CHARACTERISTICS The l denotes the specications which apply over the full operating temperature
range, otherwise specications are at TA = 25°C. (Note 3)
Note 7: The converter uses the internal oscillator.
Note 8: The converter is in external SCK mode of operation such that the
SCK pin is used as a digital input. The frequency of the clock signal driving
SCK during the data output is fESCK and is expressed in Hz.
Note 9: The converter is in internal SCK mode of operation such that the
SCK pin is used as a digital output. In this mode of operation, the SCK pin
has a total equivalent load capacitance of CLOAD = 20pF.
Note 10: The external oscillator is connected to the fO pin. The external
oscillator frequency, fEOSC, is expressed in kHz.
Note 11: The converter uses the internal oscillator. fO = 0V.
Note 12: Guaranteed by design and test correlation.
Note 13: There is an internal reset that adds an additional 1μs (typical) to
the conversion time.
