may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

they will be clamped by internal diodes. These products can handle input

otherwise noted.

Note 5: Linearity, offset and full-scale specifications apply for a

single-ended analog input with respect to COM.

Note 6: Integral nonlinearity is defined 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: Bipolar zero error is the offset voltage measured from –0.5LSB

when the output code flickers between 0000 0000 0000 and 1111 1111

1111. Unipolar zero error is the offset voltage measured from +0.5LSB

when the output code flickers between 0000 0000 0000 and 0000 0000

0001.

Note 8: Full-scale bipolar error is the worst-case of –FS or +FS untrimmed

deviation from ideal first and last code transitions and includes the effect

of offset error. Unipolar full-scale error is the deviation of the last code

transition from ideal and includes the effect of offset error.

Note 9: Guaranteed by design, not subject to test.

Note 10: All specifications in dB are referred to a full-scale ±2.048V input

with a 2.5V reference voltage.

Note 11: Full linear bandwidth is defined as the full-scale input frequency

at which the SINAD degrades to 60dB or 10 bits of accuracy.

Note 13: REFCOMP wake-up time is the time required for the REFCOMP

pin to settle within 0.5LSB at 12-bit resolution of its final value after

waking up from SLEEP mode.
