Note 5: Matching parameters are the difference between amplifiers A and
D and between B and C on the LT1633; between the two amplifiers on the
LT1632.
Note 6: Output voltage swings are measured between the output and
power supply rails.
Note 7: V

5V tests.
Note 8: V

±15V tests.
Note 9: Minimum supply voltage is guaranteed by testing the change of
V

to be less than 250µV when the supply voltage is varied from 3V to
2.7V.
The
● 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: 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 LT1632C/LT1633C are guaranteed to meet specified
performance from 0°C to 70°C and are designed, characterized and
expected to meet these extended temperature limits, but are not tested at
–40°C and 85°C. Guaranteed I grade parts are available, consult factory.
