*Note: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
Absolute Maximum Ratings
This is a stress rating only and functional operation of the devices at those or any other conditions above those
indicated in the operation listings of this specification is not implied. Exposure to maximum rating conditions for
extended periods may affect device reliability.

Due to special I/O design requirements of the High Voltage Difference Amplifier, undue electrical over-voltage
stress (i.e., ESD) experienced by these pads may result in impedance degradation of these inputs (HVAIN+
and HVAIN–). For this reason, care should be taken to ensure proper handling and use as typically required to
prevent ESD damage to electrostatically sensitive CMOS devices (e.g., static-free workstations, use of
grounding straps, over-voltage protection in end-applications, etc.)
