Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The inputs are protected by back-to-back diodes. If the differential
input voltage exceeds 0.7V, the input current should be limited to less than
10mA.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum.
Note 4: Thermal resistance varies depending upon the amount of PC board
metal attached to the device.
covered with 2 oz copper on both sides.
Note 5: Input offset voltage is exclusive of warm-up drift.

Note 6: Slew rate is measured between 2V on a 4V output with 6V
supplies, and between 1V on a 1.5V output with 2.5V supplies. Falling
slew rate is guaranteed by correlation to rising slew rate.
Note 7: Full power bandwidth is calculated from the slew rate:
FPBW = SR/2 V
Note 8: This parameter is not 100% tested.
Note 9: The LT1969C is guaranteed to meet specified performance from 0 C
to 70 C. The LT1969C 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.
Note 10: The LT1969C is guaranteed functional over the operating temperature
range of –40 C to 85 C.
