Note 1
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur DC and AC electrical specifications do not apply when operating
the device beyond its specified operating ratings
Note 2
When the input voltage exceeds the power supplies the current should be limited to 1 mA
Note 3
The maximum power dissipation must be derated at elevated temperatures and is dictated by TJ MAX iJA and the ambient temperature TA The maximum
allowable power dissipation at any temperature is PD e (TJ MAX b TA) iJA or the number given in the Absolute Maximum Ratings whichever is lower For
guaranteed operation TJ max e 125 C The typical thermal resistance (iJA) of the LF451CM when board-mounted is 170 CW
Note 5
See AN-450 ‘‘Surface Mounting Methods and Their Effect on Product Reliability’’ (Appendix D) for other methods of soldering surface mount devices
Note 6
Typicals are at TJ e 25 C and represent most likely parametric norm
