DIGITAL INPUTS AND DIGITAL OUTPUTS The ● denotes the specications which apply over the
full operating temperature range, otherwise specications are at TA = 25°C. (Note 3)
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: Unless otherwise specied:
VCC = 2.7V to 5.5V
VREFCM = VREF/2, FS = 0.5VREF
VIN = IN+ – IN–, VIN(CM) = (IN+ – IN–)/2,
where IN+ and IN– are the selected input channels.
Note 4: Use internal conversion clock or external conversion clock source
with fEOSC = 307.2kHz unless other wise 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.
Note 7: fEOSC = 256kHz ±2% (external oscillator).
Note 8: fEOSC = 307.2kHz ±2% (external oscillator).
Note 9: Simultaneous 50Hz/60Hz (internal oscillator) or fEOSC = 280kHz
±2% (external oscillator).
Note 10: The SCK can be congured in external SCK mode or internal SCK
mode. In external SCK mode, the SCK pin is used as a digital input and the
driving clock is fESCK. In the internal SCK mode, the SCK pin is used as a
digital output and the output clock signal during the data output is fISCK.
Note 11: The external oscillator is connected to the FO pin. The external
oscillator frequency, fEOSC, is expressed in kHz.
Note 12: The converter uses its internal oscillator.
Note 13: The output noise includes the contribution of the internal
calibration operations. VREF ≤ VCC.
Note 14: Guaranteed by design and test correlation.
Note 15: 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 16: Refer to Applications Information section for performance vs
data rate graphs.
Note 17: The converter in internal SCK mode of operation such that the
SCK pin is used as a digital output.
Note 18: For VCC < 3V, VIH is 2.5V for pin fO.
