The
G
denotes specifications that apply over the full operating
temperature range.
Note 1
: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
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 indefinitely.
Note 4
: The LT1468C 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 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/2
π
V
P
Note 7
: This parameter is not 100% tested.
