Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
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 5: Full power bandwidth is calculated from the slew rate
measurement: FPBW = (SR)/2πV
P
.
Note 6: This parameter is not 100% tested.
Note 7: The LT1355C/LT1356C/LT1356I are guaranteed functional over the
operating temperature range of –40°C to 85°C. The LT1356H is guaranteed
functional over the operating temperature range of –40°C to 125°C case
temperature (T
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. The
LT1356I is guaranteed to meet specified performance from –40°C to
85°C. The LT1356H is guaranteed to meet specified performance from
–40°C to 125°C case temperature (T
C
). The parts are pulse tested at
these temperatures. Internal warm-up drift must be taken into account
separately. Care must be taken not to exceed the maximum junction
temperature.
