ELECTRICAL CHARACTERISTICS

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:

FPBW = SR/2

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

connected 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 SOT-23 or Pin 4 of the SO-8 to a

large metal area.

Note 10: For the 8-lead SO and 6-lead SOT-23 parts, the electrical

characteristics apply to the “ON” state, unless otherwise noted. These parts

are in the “ON” state when either SHDN is not connected,

Note 11: The shutdown (SHDN) feature is not available on the 5-lead

SOT-23 parts. These parts are always in the “ON” state.
