Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Differential inputs of ±10V are appropriate for transient operation
only, such as during slewing. Large, sustained differential inputs will cause
excessive power dissipation and may damage the part. See Input
Considerations in the Applications Information section of this data sheet
for more details.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 4: Slew rate is measured between ±10V on the output with ±6V input
for ±15V supplies and ±1V on the output with ±1.75V input for ±5V
supplies.

Note 6: This parameter is not 100% tested.
Note 7: The LT1355C/LT1356C are guaranteed functional over the
operating temperature range of –40°C to 85°C.
Note 8: The LT1355C/LT1356C are guaranteed to meet specified
performance from 0°C to 70°C. The LT1355C/LT1356C are designed,
characterized and expected to meet specified performance from –40°C to
85°C, but are not tested or QA sampled at these temperatures. For
guaranteed I-grade parts, consult the factory.
