ELECTRICAL CHARACTERISTICS
The l denotes the specifi cations which apply over the full operating
temperature range, otherwise specifi cations are at T
A
= 25°C. –40°C ≤ T
A
≤ 85°C, V
CM
= 0V unless otherwise noted.
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: The inputs are protected by back-to-back diodes and two 100
series resistors. If the differential input voltage exceeds 0.7V, the input
current should be limited to 10mA. Input voltages outside the supplies will
be clamped by ESD protection devices and input currents should also be
limited to 10mA.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefi nitely.

Note 4: The LT1468C is guaranteed to meet specifi ed performance from
0°C to 70°C and is designed, characterized and expected to meet these
extended temperature limits, but is not tested at –40°C and at 85°C. The
LT1468I is guaranteed to meet the extended temperature limits.
Note 5: 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 6: Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2πV
P
Note 7: This parameter is not 100% tested.
