Note 1: Absolute Maximum Ratings are those values beyond which the life of
the device may be impaired.
Note 2: Differential inputs of 3V are appropriate for transient operation only,
such as during slewing. Large sustained differential inputs can cause
excessive power dissipation and may damage the part.
Note 3: A heat sink may be required to keep the junction temperature below
absolute maximum when the output is shorted indefinitely.
Note 4: Input offset voltage is pulse tested and is exclusive of warm-up drift.
Note 5: Slew rate is measured between 2V on the output with 3V input for
supplies.

Note 6: Full power bandwidth is calculated from the slew rate:
Note 7: This parameter is not 100% tested.
Note 8: The LT1812C is guaranteed to meet specified performance from
0 C to 70 C. The LT1812C is designed, characterized and expected to meet
specified performance from –40 C to 85 C but is not tested or QA sampled
at these temperatures. The LT1812I is guaranteed to meet specified
performance from –40 C to 85 C.
Note 9:
both sides. Thermal resistance varies, depending upon the amount of PC
board metal attached to the device. For this package in particular, power is
dissipated primarily through Pin 4, which should therefore, have a good
thermal connection to a copper plane.
