Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating

conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.

(3)

This value is limited to 2.5 V maximum.

(4)

The package thermal impendance is calculated in accordance with JESD 51-7.

The RESET and Cn inputs of the device must be held at valid logic voltage levels (not floating) to ensure proper device operation. The

differential inputs must not be floating, unless RESET is low. Refer to the TI application report, Implications of Slow or Floating CMOS

Inputs, literature number SCBA004.
