Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The inputs are protected from ESD with diodes to the supplies.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum.
Note 4: The LT6552C/LT6552I are guaranteed functional over the
temperature range of –40°C to 85°C.
Note 5: The LT6552C is guaranteed to meet specified performance from
0°C to 70°C and is designed, characterized and expected to meet specified
performance from –40°C to 85°C, but is not tested or QA sampled at these
temperatures. The LT6552I is guaranteed to meet specified performance
from – 40°C to 85°C.
Note 6: When RL = 1k is specified, the load resistor is RF + RG, but when
RL = 150Ω or RL = 75Ω is specified, then an additional resistor of that
value is added to the output.
Note 7: VOS measured at the output (Pin 6) is the contribution from both
input pairs and is input referred.
Note 8: Minimum supply is guaranteed by the PSRR test.
Note 9: Full power bandwidth is calculated from the slew rate.
FPBW = SR/2πVp
Note 10: VS = 3.3V, tr and tf limits are guaranteed by correlation to
VS = 5V and ±5V tests.
