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 ground.
Note 3:
When these pin voltages are taken below ground or above V
DD
or
OV
DD
, they will be clamped by internal diodes. This product can handle
input currents up to 100mA below ground or above V
DD
or OV

without
latch-up.
Note 4:
V
DD

DD
= 2.5V, ±10.24V Range, REFIN = 2.048V,
f
SMPL
= 500kHz.
Note 5:
Recommended operating conditions.
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 00 0000 0000 0000 0000 and 11
1111 1111 1111 1111. 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.
Note 8:
All specifications in dB are referred to a full-scale ±20.48V input
with REFIN = 2.048V.
Note 9:
When REFBUF is overdriven, the internal reference buffer must be
turned off by setting REFIN = 0V.
Note 10:
f
SMPL
= 500kHz, I
REFBUF
varies proportionally with sample rate.
Note 11:
Guaranteed by design, not subject to test.

and OV
DD

Note 13:
t
SCK
of 10ns maximum allows a shift clock frequency up to
100MHz for rising edge capture.
Note 14:
Temperature coefficient is calculated by dividing the maximum
change in output voltage by the specified temperature range.
