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 ±8V on the output with ±12V
input for ±15V supplies and ±2V on the output with ±3V input for ±5V
supplies.
Note 5: Full-power bandwidth is calculated from the slew rate
measurement: FPBW = (Slew Rate)/2πV
P
.
Note 6: This parameter is not 100% tested.
Note 7: The LT1352C/LT1353C are guaranteed to meet specified
performance from 0°C to 70°C. The LT1352C/LT1353C 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.
The LT1352I/LT1353I are guaranteed to meet specified performance
from␣ –40°C to 85°C.
