(1)

Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply

functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions.

If used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully

functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.

(2)

For input stage gains other than unity gain (GIN = 1), to protect the inputs in case of unexpected high input voltages, implement

external input series resistors. See Applications section.

(3)

Signal differential input voltage limitations still apply.

(4)

Short-circuit to VS / 2.

7.2 ESD Ratings

Charged-device model (CDM), per ANSI/ESDA/JEDEC JS-002(2)

±750

(1)

JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.

(2)

JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
