LT1813
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Differential inputs of
±3V 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 on the output with ±3V input
for
±5V supplies and 2VP-P on the output with a 3VP-P input for single 5V
supplies.
Note 6: Full power bandwidth is calculated from the slew rate:
FPBW = SR/2
πVP.
Note 7: This parameter is not 100% tested.
Note 8: The LT1813C is guaranteed to meet specified 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 85°C. The
LT1813I is 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.
ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the temperature range
–40
°C ≤ TA ≤ 85°C. VS = ±5V, VCM = 0V unless otherwise noted (Notes 8, 9).
