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: When these pin voltages are taken below VSS they will be clamped
by internal diodes. This product can handle input currents greater than
100mA below VSS without latchup. GAIN is not clamped to VDD. When CLK
is taken above VDD, it will be clamped by an internal diode. The CLK pin
can handle input currents of greater than 100mA above VDD without
latchup.
Note 5: VDD = 5V, VSS = – 5V or 0V, fSAMPLE = 10MHz, tr = tf = 5ns unless
otherwise specified.
Note 6: Dynamic specifications are guaranteed for dual supply operation
with a single-ended + AIN input and – AIN grounded. For single supply
dynamic specifications, refer to the Typical Performance Characteristics.
Note 7: 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 8: Bipolar offset is the offset voltage measured from –0.5LSB
when the output code flickers between 0000 0000 0000 and
1111 1111 1111.
Note 9: Guaranteed by design, not subject to test.
Note 10: Recommended operating conditions.
The
● denotes the specifications which apply over the full operating temperature
range, otherwise specifications are at TA = 25°C. Specifications are guaranteed for both dual supply and single supply operation.
