Note 1: Stresses beyond those listed under Absolute Maximum Ratings may
cause permanent damage to the device. Exposure to any Absolute Maximum
Rating condition for extended periods may affect device reliability and lifetime.
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
±5V supplies and 2VP-P on the output with a 3VP-P input for single 5V supplies.
Note 6: Full power bandwidth is calculated from the slew rate: FPBW = SR/2πVP.
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: Thermal resistance varies with the amount of PC board metal conn-
ected to the package. The nominal values are for short traces connected to the
pins. The thermal resistance can be substantially reduced by connecting Pin 2
of the 5-lead or 6-lead TSOT-23 or Pin 4 of the SO-8 to a large metal area.
Note 10: For the 8-lead SO and 6-lead TSOT-23 parts, the electrical charac-
teristics apply to the “ON” state, unless otherwise noted. These parts are in
the “ON” state when either SHDN is not connected, or SHDN > V– + 2.0V.
Note 11: The shutdown (SHDN) feature is not available on the 5-lead
SOT-23 parts. These parts are always in the “ON” state.
