Differential inputs of ± 3V are appropriate for transient operation sampled at these temperatures. The LT1812I is guaranteed to meet specifi ed only, such as during slewing. Large sustained differential inputs can cause performance from –40°C to 85°C. excessive power dissipation and may damage the part.

Input offset voltage is pulse tested and is exclusive of warm-up drift. of the 5-lead or 6-lead TSOT-23 or Pin 4 of the SO-8 to a large metal area.
Note 5:
Slew rate is measured between ±2V on the output with ±3V input for
