[1] The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed.
[2] The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability.
[3] For SO20 packages: above 70 ˚C derate linearly with 8 mW/K.
For SSOP20 and TSSOP20 packages: above 60 ˚C derate linearly with 5.5 mW/K.
For DHVQFN20 packages: above 60 ˚C derate linearly with 4.5 mW/K.
