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 = 2.7V to 5.5V unless otherwise specied:
VREFCM = VREF/2, FS = 0.5VREF
VIN = IN+ – IN, VIN(CM) = (IN+ + IN)/2
Note 4: Use internal conversion clock or external conversion clock source
with fEOSC = 307.2kHz 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.
Note 7: fEOSC = 256kHz ±2% (external oscillator).
Note 8: fEOSC = 307.2kHz ±2% (external oscillator).
Note 9: Simultaneous 50Hz/60Hz rejection (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 digital input and the
driving clock is fESCK. In internal SCK mode, the SCK pin is used as 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 the internal oscillator.
Note 13: The output noise includes the contribution of the internal
calibration operations.
Note 14: Guaranteed by design and test correlation.
Note 15: Refer to Applications Information section for performance vs
data rate graphs.
Note 16: For VCC < 3V, VIH is 2.5V for pin fO.
