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 VSS or above VDD, they
will be clamped by internal diodes. This product can handle input currents
greater than 100mA below VSS or above VDD without latchup.
Note 4: VDD = 5V, VSS = –5V or 0V, fSAMPLE = 6MHz, tr = tf = 5ns unless
otherwise specified.
Note 5: Linearity, offset and full-scale specifications apply for a
single-ended +AIN input with – AIN tied to VCM for single supply and 0V for
dual supply.
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 offset is the offset voltage measured from –0.5LSB
when the output code flickers between 00 0000 0000 0000 and
11 1111 1111 1111.
Note 8: Guaranteed by design, not subject to test.
Note 9: Recommended operating conditions.
