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
indefinitely.
Note 3: This parameter is not 100% tested.
Note 4: The LT1498C/LT1499C are guaranteed to meet specified
performance from 0°C to 70°C. The LT1498C/LT1499C are designed,
characterized and expected to meet specified performance from –40°C
to 85°C but are not tested or QA sampled at these temperatures. The
LT1498I/LT1499I are guaranteed to meet specified performance from
–40°C to 85°C. The LT1498MP is guaranteed to meet specified
performance from –55°C to 125°C.
Note 5: Matching parameters are the difference between amplifiers A and
D and between B and C on the LT1499; between the two amplifiers 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.
