Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a 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:
With
±5V
supplies, slew rate is tested in a closed-loop gain of –1
by measuring the rise time of the output from –2V to 2V with an output
step from –3V to 3V. With single 5V supplies, slew rate is tested in a
closed-loop gain of –1 by measuring the rise time of the output from 1.5V
to 3.5V with an output step from 1V to 4V. Falling edge slew rate is not
production tested, but is designed, characterized and expected to be within
10% of the rising edge slew rate.
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 LT1818C/LT1818I and LT1819C/LT1819I are guaranteed
functional over the operating temperature range of – 40°C to 85°C.
Note 9:
The LT1818C/LT1819C 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 LT1818I/LT1819I are guaranteed to meet the
extended temperature limits.
