TYPICAL PERFOR U
Note 1:
Absolute Maximum Ratings are those values beyond which the life of
a device may be impaired.
Note 2:
All voltage values are with respect to ground with GND and OGND
wired together (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.

with differential drive, unless otherwise noted.
Note 5:
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 6:
Offset error is the offset voltage measured from –0.5 LSB when the
output code flickers between 00 0000 0000 and 11 1111 1111 in 2’s
complement output mode.
Note 7:
Guaranteed by design, not subject to test.

Note 10:
SNR minimum and typical values are for LVDS mode. Typical values
for CMOS mode are typically 0.7dB to 0.9dB lower.
Note 11:
SFDR minimum values are for LVDS mode. Typical values are for
both LVDS and CMOS modes.
Note 12:
SINAD minimum and typical values are for LVDS mode. Typical
values for CMOS mode are typically 0.5dB to 0.9dB lower.
