ELECTRICAL CHARACTERISTICS
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: A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indenitely.
Note 3: This parameter is not 100% tested.
Note 4: The LT1498C/LT1499C are guaranteed to meet specied
performance from 0°C to 70°C. The LT1498C/LT1499C are designed,
characterized and expected to meet specied performance from –40°C
to 85°C but are not tested or QA sampled at these temperatures. The
LT1498I/LT1499I are guaranteed to meet specied performance from
–40°C to 85°C. The LT1498H/LT1499H are guaranteed to meet specied
performance from –40°C to 125°C. The LT1498MP is guaranteed to meet
specied performance from –55°C to 125°C.

The
l denotes the specications which apply over the temperature range
–55°C < TA < 125°C. VS = ±15V, VCM = 0V, VOUT = 0V, unless otherwise noted. (Note 4)
Note 5: Matching parameters are the difference between ampliers A and
D and between B and C on the LT1499; between the two ampliers on the
LT1498.
Note 6: Output voltage swings are measured between the output and
power supply rails.
Note 7: VS = 3V, VS = ±15V GBW limit guaranteed by correlation to
5V tests.
Note 8: VS = 3V, VS = 5V slew rate limit guaranteed by correlation to
±15V tests.
