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 VDD, they

will be clamped by internal diodes. This product can handle input currents

of greater than 100mA below GND or above VDD without latchup.

Note 4: VDD = 3.3V, fSAMPLE = 20MHz, input range = 2.5VP-P with

differential drive (PGA = 0), unless otherwise speciﬁed.

Note 5: Integral nonlinearity is deﬁned as the deviation of a code from a

“best ﬁt 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 ﬂickers 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 < 1kΩ.
