TIMING CHARACTERISTICS
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, with GND and OGND
shorted (unless otherwise noted).
Note 3: When these pin voltages are taken below GND or above V
DD
, they
will be clamped by internal diodes. This product can handle input currents
of greater than 100mA below GND or above V
DD
without latchup.
Note 4: V

with differential drive (PGA = 0), unless otherwise
specifi ed.
Note 5: Integral nonlinearity is defi ned as the deviation of a code from a
“best fi t straight line” to the transfer curve. The deviation is measured from
the center of the quantization band.
Note 6: Offset error is the offset voltage measured from –1/2LSB when the
output code fl ickers between 0000 0000 0000 0000 and 1111 1111 1111
1111 in 2’s complement output mode.
Note 7: Guaranteed by design, not subject to test.
Note 8: Recommended operating conditions.
Note 9: Dynamic current from switched capacitor inputs is large compared
to DC leakage current, and will vary with sample rate.
Note 10: Leakage current will experience transient at power up. Keep
resistance < 1K Ω.
