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 LT1630C/LT1631C are guaranteed to meet specified
performance from 0°C to 70°C. The LT1630C/LT1631C and 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
LT1630I/LT1631I are guaranteed to meet specified performance from
–40°C to 85°C. The LT1630H is guaranteed to meet specified performance
from –40°C to 125°C.
Note 5: Matching parameters are the difference between amplifiers A and
D and between B and C on the LT1631; between the two amplifiers on the
LT1630.
Note 6: Output voltage swings are measured between the output and
power supply rails.
Note 7: V

5V tests.
Note 8: V

S
= 5V slew rate limit guaranteed by correlation to
±15V tests.
Note 9: Minimum supply voltage is guaranteed by testing the change of
V
OS
to be less than 250µV when the supply voltage is varied from 3V to
2.7V.
