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 HJA and the ambient temperature TA The

maximum allowable power dissipation at any temperature is PD e (TJ MAX b TA) HJA or the number given in the Absolute Maximum Ratings whichever is lower

For guaranteed operation TJ max e 125 C The typical thermal resistance (HJA) of the LF453CM when board-mounted is 160 CW

Note 4

See AN-450 ‘‘Surface Mounting Methods and Their Effect on Product Reliability’’ (section titled ‘‘Surface Mount’’) for other methods of soldering surface

mount devices

Note 5

Typicals are at TJ e 25 C and represent most likely parametric norm

Note 6

Tested limits are guaranteed to National’s AOQL (Average Outgoing Quality Level)

Note 7

Design limits are guaranteed to National’s AOQL but not 100% tested

Note 8

The input bias currents are junction leakage currents which approximately double for every 10 C increase in the junction temperature TJ Due to limited

production test time the input bias currents are correlated to junction temperature In normal operation the junction temperature rises above the ambient

temperature as a result of internal power dissipation PD TJ e TA a HJA PD where HJA is the thermal resistance from junction to ambient

Note 9

VOS IB AVOL and IOS are measured at VCM e 0V

Note 10

Supply voltage rejection ratio is measured for both supply magnitudes increasing or decreasing simultaneously in accordance with common practice
