(1)Stresses above these ratings may cause permanent damage.
Exposure to absolute maximum conditions for extended periods
may degrade device reliability. These are stress ratings only, and
functional operation of the device at these or any other conditions
beyond those specified is not supported.

This integrated circuit can be damaged by ESD. Texas
Instruments recommends that all integrated circuits be
handled with appropriate precautions. Failure to observe
proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to
complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could
cause the device not to meet its published specifications.

Interchannel Gain Mismatch
Interchannel Phase Deviation
(1)Dynamic performance is measured with an Audio Precision System Two Cascade or Cascade Plus test system.
(2)fsMIN = min (fsIN, fsOUT).
(3)fsMAX = max (fsIN, fsOUT).
(4)Power-supply current for the power-down modes is measured without loading.
(5)Dynamic power-supply current measurements are performed with 2mA active loads on the excercized outputs.
