(1) Absolute Maximum Ratings are those values beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications and test
conditions, see the Electrical Characteristics.
(2) The maximum power dissipation must be de-rated at elevated temperatures (only needed for TA>85°C) and is limited by TJMAX
(maximum junction temperature), θJ-A (junction to ambient thermal resistance) and TA(ambient temperature). θJ-A is 140°C/W for the
SOIC-8 package and 220°C/W for the VSSOP-8 package. The maximum power dissipation at any temperature is:PDissMAX = (TJMAX −
TA)/θJ-A up to the value listed in the Absolute Maximum Ratings.
Operating Ratings Human Body Model 2 kV
ESD Susceptibility(1) Machine Model 200V
Ambient Temp. Range −40°C to +85°C
Junction Temp. Range −40°C to +125°C
(1) The human body model is a 100 pF capacitor discharged through a 1.5 kΩresistor into each pin. The machine model is a 200pF
capacitor discharged directly into each pin.
