NOTES

1Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. This is a stress rating; functional operation of the device

at these or any other conditions above those listed in the operational sections of this

specification is not implied. Exposure to absolute maximum rating conditions for

extended periods may affect device reliability.

2Maximum terminal current is bounded by the maximum current handling of the

switches, maximum power dissipation of the package, and maximum applied

voltage across any two of the B and W terminals at a given resistance.

3Includes programming of nonvolatile memory.

4Applicable to TSSOP-16 only. For LFCSP-16, please consult factory for details.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily

accumulate on the human body and test equipment and can discharge without detection. Although

the ADN2850 features proprietary ESD protection circuitry, permanent damage may occur on

devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are

recommended to avoid performance degradation or loss of functionality.

WARNING!
