ESD

Human Body Model

2 kV

Charged Device Model

1.25 kV

Machine Model

0.2 kV

1 For voltages beyond these limits, use input protection resistors. See the

Theory of Operation section for more information.

2 There are ESD protection diodes from the reference input to each supply, so

REF cannot be driven beyond the supplies in the same way that +IN and −IN

can. See the Reference Terminal section for more information.

Stresses above those listed under Absolute Maximum Ratings

may cause permanent damage to the device. This is a stress

rating only; functional operation of the device at these or any

other conditions above those indicated in the operational

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

THERMAL RESISTANCE

θJA is specified for a device in free air using a 4-layer JEDEC

printed circuit board (PCB).
