Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: Differential inputs of ±6V are appropriate for transient operation
only, such as during slewing. Large sustained differential inputs can cause
excessive power dissipation and may damage the part.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 4: Input offset voltage is pulse tested and is exclusive of warm-up
drift.
Note 5: Slew rate is measured between ±2V at the output with ±3V input
for ±5V supplies and 2V
P-P
at the output with a 3V
P-P
input for single 5V
supplies.
Note 6: Full power bandwidth is calculated from the slew rate:
FPBW = SR/2πV
P
Note 7: This parameter is not 100% tested
Note 8: The LT1813C/LT1814C are guaranteed to meet specified
performance from 0°C to 70°C and is designed, characterized and
expected to meet the extended temperature limits, but is not tested at
–40°C and 85°C. The LT1813I/LT1814I are guaranteed to meet the
extended temperature limits.
Note 9: The LT1813D is 100% production tested at 25°C. It is designed,
characterized and expected to meet the 0°C to 70°C specifications
although it is not tested or QA sampled at these temperatures. The
LT1813D is guaranteed functional from –40°C to 85°C but may not meet
those specifications.
Note 10: Propagation delay is measured from the 50% point on the input
waveform to the 50% point on the output waveform.
