LT1357
ELECTRICAL CHARACTERISTICS
The ● denotes specifications that apply over the full specified temperature
range.
Note 1: 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 2: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 3: 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 4: Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2πV
P
.
Note 5: This parameter is not 100% tested.
Note 6: The LT1357 is designed, characterized and expected to meet these
extended temperature limits, but is not tested at –40°C and at 85°C.
Guaranteed I grade parts are available; consult factory.
